List of Diary of a Wimpy Kid characters

Gregory "Greg" Heffley is 11 years old in the first novel. Greg's actions can be antagonistic at times, including terrorizing kids, trying to steal money from a church collection basket, lying in confession, picking on other students, playing pranks on his best friend, selling falsely advertised "fitness water," and praying for bad stuff to happen to others. He also is a very bad friend. However, he also demonstrates a degree of kindness in some of his actions. He helps his brother with his homework, gets his friend a date for a dance, and forgives his friends.

Greg is portrayed by Zachary Gordon in the first three films, and Jason Drucker in the fourth film.

Rowley Jefferson is Greg's best friend. In the first book, Rowley is 11 years old and an antagonist in Greg's point of view while technically in a third-person view, Greg is the antagonist and Rowley is the protagonist. At the end of Diary of a Wimpy Kid: The Third Wheel, Rowley begins dating Abigail Brown, a girl who was originally Greg's date for the Valentine's Day dance. This plot continues in Diary of a Wimpy Kid: Hard Luck, where he ditches Greg for his new girlfriend Abigail. At the end of the book, the couple breaks up and he becomes friends with Greg again.

Rowley has what Greg considers strange interests for his age and gender, such as loving a singer for "six-year-old girls" named Joshie and action figures Greg believes are for younger kids. Rowley is also the owner of the comic strip Zoo Wee Mama.[4] Rowley thinks that Greg had nothing to do with the comic strip in the first book, a rare antagonistic move from him.

In the movie series, Rowley is portrayed by Robert Capron, in the first three movies and Owen Asztalos in The Long Haul.

Frank Heffley is Greg's overactive but well-meaning father. He is 40 years old in the first book and is interested in U.S. history, with his replica of a Civil War battlefield serving as a recurring plot point in the series.[5] Frank is rude around Rowley,[5] does not appreciate Greg's skill at video games, loathes heavy metal,[4] and adolescents.[6] He tries to toughen Greg up and threatens to send him to a military academy in The Last Straw, although ultimately this does not come to fruition, much to Greg's relief.[6] However, Greg and Frank grow together in Dog Days, despite a brief period when Frank does not speak to Greg after almost getting arrested and going to jail.

Frank is addicted to junk food; in The Last Straw, he makes a New Year's Resolution to go on a strict diet, but Greg later catches him in the garage eating brownies. After Greg is forced to go for several days without any snacks due to a thief taking them, he eventually decides to catch the thief, and discovers that it is Frank.

Frank is portrayed by Steve Zahn in the first three films of the Diary of a Wimpy Kid film series. In Diary of a Wimpy Kid: The Long Haul, he's played by Tom Everett Scott.

Susan Heffley (known as Ann Heffley in the online version) is the mother of Manny, Gregory, and Rodrick, the wife of Frank and a homemaker. She is a loving and caring mother but can be embarrassing, bossy, hypocritical, dimwitted, overprotective, and naive. Susan doesn't like technology, thinking it causes people to not socialize. She seems to have a very small knowledge of kids Rodrick and Greg's age and constantly humiliates and ignores them. She constantly tries to get the family together which never works out. She and her husband Frank also shows immense favoritism towards their youngest son Manny.

Susan is portrayed by Rachael Harris in the first three films and Alicia Silverstone in the fourth film.

Manny Heffley is Greg and Rodrick's three-year-old brother who is constantly spoiled and pampered by his parents. Manny has many uncaring and selfish grudges like nearly killing the family by knocking out the power of the house in Cabin Fever and having tantrums when not getting things his way. It is also likely Manny knows his parents' favoritism towards him and he often takes advantage of it like making money out of the no swearing rule, breaking Greg's items and getting away with it, never getting in trouble for his actions and often passing the blame towards Greg or Rodrick, etc. Despite being a spoiled three year old, Manny has proven to have more intelligence then he poses like figuring out how to sell all of Greg's items in Net Kritterz account and managed to change the password and locks out the whole family from watching TV by using the parental lock to only watch his favourite cartoons. However, Manny's strange behavior can also help the family as in the Long Haul he speaks fluent Spanish to help the family get home.

He is played by Connor and Owen Fielding in the first three films and is played by Dylan and Wyatt Walters in the Long Haul.

Rodrick Heffley is Greg's lazy and aggressive older brother. He is 16 years old in the first book and he is the drummer in a garage band called "Löded Diper" (loaded diaper), noted for their substandard heavy metal concerts and limited musical abilities. Rodrick is not an exception to Frank's notorious distrust of all teenagers.

Rodrick is infamous for his stereotypical rebellious nature, feigning illness in Rodrick Rules so as to be allowed to remain at home to throw a chaotic house party during his parents' absence, only for the evidence to appear in newly developed photographs that are discovered by the boys' parents just after Thanksgiving. He bullies Greg a lot and pulls awful pranks that ruin Greg's and his family's life. Rodrick also possesses incompetent tendencies, as his school assignments are notoriously crude and inadequate. Rodrick also makes numerous idiotic mistakes, such as believing a mini-safe is a microwave and cinnamon bun dough which had exploded all over the car was his brains. His spelling abilities are also poor, and he devotes a lot of time to tormenting Greg. He also does not know how to type, and on one occasion, when he has to type one of his assignments, he types one letter a minute and repeatedly has to ask Frank where the space bar is. In the books, Rodrick owns and drives a white van, which sports his band's name written in large black letters, on either side of it and lacks any back seats, the reason being that Rodrick needs room for his band equipment. In the movie series, the van is revealed to be a 1996 Chevrolet Astro AWD van, which also sports a diaper's pin drawn on the rear doors. In Rodrick Rules, Greg is haunted by the fact that Rodrick knows about his most mortifying experience during the summertime. This haunts him when he returns to school. However, his fears are quickly eased after the story becomes distorted to Greg's advantage due to it being passed around by so many people, temporarily boosting his popularity. By the end of the film adaptation of Rodrick Rules, he is much closer to Greg, and his actions to him become much less aggressive. This is also shown in the film adaptation of Dog Days when Rodrick thanks Greg for getting him a gig at Heather Hills' Sweet 16, also this was not seen in the book.

In the first three films in the film series based on the books, Rodrick is played by Devon Bostick. In the fourth film, Diary of a Wimpy Kid: The Long Haul, Rodrick is played by Charlie Wright.

Gramma is Susan's mother and Greg's maternal grandmother. Gramma is known to drive a car like the Heffleys'. Greg often calls her to his home as a way to avoid his dad's scoldings, since his father will not do this when she is around. Her favorite grandchild is Manny, although she denies and lies about this despite overwhelming evidence in the form of pictures on her refrigerator and many of Manny's drawings around her house. She also seems to have a passion for bingo and knitting. Gramma has a dog named Sweetheart, usually shortened to Sweetie. It has been said and shown that she overfeeds Sweetie.

Grandpa is Greg's unpredictable paternal grandfather, who is asked to babysit Rodrick and his brother in Rodrick Rules. He lives in a retirement home called Leisure Towers and enjoys playing games such as "Gutbusters" and "Rummy", which the two boys find boring. He never watches any real shows on the television; instead he constantly has his television tuned to the CCTV in the retirement home lobby, which he spends his time watching. In Old School, he moves out of Leisure Towers because the rent is too high and moves in with the Heffleys. Grandpa has a girlfriend named Darlene in the Hard Luck and broke up with her in Old School. Grandpa dates online. Grandpa eventually accumulates a large number of girlfriends online, culminating in him accidentally inviting all of them over and throwing a party with them. Greg is his favorite. Grandpa is known for preparing what he calls "Watercress Salad", a disgusting dish consisting of cold green beans and cucumbers floating in vinegar. Greg hates Watercress Salad, and Rodrick is aware of this, so he pretends that Greg loves it and puts a large helping onto his plate. It's stated that Grandpa never spent much time with Frank when he was a boy, and they seem to have a poor relationship. Grandpa once accidentally ran over Frank's dog with his car and lied to him about it (claiming that the dog ran away) before telling him many years later, expecting a laugh, and constantly criticizes Frank during his stay at the Heffleys' house. He has not been seen since Double Down, implying that he possibly moved out.

Joseph "Joe" Heffley is Frank's brother and Greg's uncle. Frank has a sibling rivalry with Joe due to his actions. When Manny started potty training, Uncle Joe told him to watch out for the "potty monster", causing him to fear using the bathroom, forcing Frank to change his diapers for a longer time. Uncle Joe's children call their uncle "Aunt Fwank", which Frank swears he told them to do on purpose. Susan thinks it's cute, though. In Dog Days, Greg mentions that he tried to make Uncle Joe convince Frank to get a dog, but that did not work out. He also mentions that Joe's dog, Killer ate most of his birthday cake.

Joe Heffley's wife is a dark-haired woman and Greg's aunt. Her name is not revealed.

Joe Heffley has at least three children, who all appear to be a bit older than Manny, and are Greg's cousins. They all call Frank "Aunt Fwank."

Charlie is Nana's brother and Greg's great uncle. He is also Greg's "secret weapon" at Christmas, as he asks him to buy him presents that his parents have forbidden him from receiving. However, this backfires as he is usually given the wrong thing. Charlie is a bachelor and spends his spare money well. Greg says he wants to follow in his footsteps. In The Last Straw, Charlie got Greg a laundry hoop, hinting that he is tired of being Greg's secret weapon at Christmas, as the events that transpired meant that Greg effectively got a chore for Christmas.

Loretta is Greg's great-aunt and the sister of Grandpa, Arthur, and Reba. She got a thank you note for some pants she gave Greg at Christmas. She appeared mainly in Rodrick Rules at the Thanksgiving dinner. She also appeared a couple of times in the Do It Yourself Book and The Ugly Truth. It is implied that Greg and Rodrick dislike her, as they fight over who has to greet her first when she visits.

Gammie is Greg's great-grandmother and the unofficial head of the Heffley family. She appears in The Ugly Truth as a major character. She also has Lego building bricks that Susan bought so that her kids had something to do at her house. Gammie is a trickster and knows a lot because of "experience". When someone in the family is about 12 or 13 years old she gives them The Talk, which is about how kids should not be hurrying to grow up.[7] Gammie loves having visitors for dinner. One day she bought a scratch ticket, and matched up two pictures and told all her family members that she had won a lot of money. Everyone was in a big rush to visit her. When they all arrived Frank told Gammie that to win, she had to match up three pictures. When she found this out, she did not care. She pulled a roast right out of the oven, and Greg figures she got what she wanted anyway. Gammie is the mother of Grandpa, Arthur, Reba, and Loretta Heffley.

Gammie is briefly mentioned by Greg in Cabin Fever when he says she gave a miniature carousel that held spoons from all over the world to Greg's family five or six years before.

Gammie returns in The Deep End and has a much smaller role. She asks Greg's family to take Uncle Gary's camper, which has been parked in her driveway for two years, and makes sandwiches for them to eat on their trip.

Reba was Greg's great-aunt. Gammie forgot to give her an invitation at Christmas, but she came anyway and refused to take off her coat. She only appeared in The Ugly Truth. She is stubborn. Reba was the sister of Grandpa, Loretta, and Arthur Heffley.[7] She and Loretta are identical twins. In Wrecking Ball, it was revealed that she died in her sleep, and Greg's family attended someone else's funeral instead of hers by mistake, and receive an inheritance of her fortune. Greg forgot about Reba at first, until Susan reminded him that she used to send him angry letters for forgetting to send her thank-you notes for his birthday money.

Garrison "Gary" Heffley is Greg's uncle and the youngest brother of Frank and Joe, who has been married four times. He was first mentioned in The Last Straw when Greg said he was out of clean laundry and was going to have to wear a shirt he got from Gary's first wedding.

Gary makes his first major appearance in The Ugly Truth. It is revealed that all of his wives divorced him as soon as they found out about his financial situation and job. He has had so many weddings that Greg's family does not need to use a growth chart.

Gary returns in The Third Wheel and has a larger role. He comes to live with Greg's family after he discovers his job selling shirts in Boston was a ripoff. Later, he is chosen to be the DJ at Greg's Valentine's Day dance and he sells his shirts to Greg's classmates. He uses his money to buy scratch tickets and wins $40,000, allowing him to move out.

In Double Down, Gary accidentally breaks his collarbone while cutting down tree branches over his driveway.

In The Deep End, Gary is never seen, but it is revealed that he used to own a camper, which had been parked in Gammie's driveway for two years. She gives it to Greg's family after being fed up with it taking up space in her driveway.

Dorothy is Greg's great aunt and the wife of Charlie, who always kisses him on the lips. Greg's mother, Susan, says it is rude to wipe off the kisses Dorothy gives him, but Greg wipes his face on the nearest available curtain when no one is looking. She is overweight and sometimes passes gas loudly.

Arthur Heffley is Greg's great-uncle. He only speaks in grunts or makes random sounds. He never has an actual conversation with anybody, but sometimes Greg tries to respond to him just in case he is trying to communicate. Arthur is the brother of Reba, Grandpa, and Loretta Heffley.[7]

Great Uncle Bruce is Greg's deceased great-uncle. He is a character who is mentioned in Cabin Fever and The Third Wheel. Greg is presented with a rather luxurious blanket as a Christmas gift, only to be repelled by it upon learning that it had formerly belonged to Great Uncle Bruce before his death. In The Third Wheel, Greg uses Great Uncle Bruce's old cologne on Valentine's Day, which ends up attracting some old ladies.

Byron is Frank's cousin whom Greg is not excited to see[7] because, at Gammie's last family meeting, they was sent out to get milk, but hit a pothole halfway home and got a flat tire. Byron told Greg to go to the house and get help. When Greg returned to Gammie's, the ladies needed to warn him of his muddy shoes because he was about to track mud into the house. Unfortunately, he forgot about Byron's tire, and he was not happy when he got to Gammie's a half-hour later.

He only appears in The Ugly Truth.

Greg's cousin, whose parents are Greg's Uncle Tony and Aunt Patricia. The last time Greg saw Benjy, he could only say "No" or "Shut up!", respectively. Now he can speak in full sentences and read chapter books but is still not potty trained and usually wears a diaper.

Frank's second cousin and the eldest son of Charlie who is said to have looked like Greg when he was his age. Greg confirms this by looking in Gammie's photo album, and strives to save money for plastic surgery.

Greg's uncle who did not appear at uncle Gary's fourth wedding because he is always traveling. He is said to almost never come to family gatherings because of this, but he sometimes makes an appearance by webcam.

Aunt Audra is one of Susan's sisters. She believes in crystal balls and took Greg along with her to see her fortuneteller a few times. Susan thinks Audra is wasting her money. The fortuneteller also told Audra that Meemaw's ring was inside a photo album. It turned out the fortuneteller did not mean it literally.

Aunt Veronica is Greg's aunt and Susan's sister. Greg states that she has never been seen in person since he was three or four years old, probably because being with the family in person stresses her out, but calls her family members on video chat. When Greg was sitting on the toilet playing games on his new phone (which was actually a hand-me-down from his mother), she accidentally started a video chat with him. This startled him, leading to him dropping the phone into the toilet. She appears in Hard Luck multiple times – often in person – but on other occasions by video conference on a tablet and the used phone that Susan gave to Greg.

Aunt Gretchen is Susan's youngest sister. She has two out-of-control twin sons, Malvin and Malcolm. Aunt Gretchen has at least thirty pets. In Hard Luck, she takes her pets with her, and her rabbit has a litter of bunnies, angering Frank since Aunt Gretchen thought her rabbit was a boy.

Malvin and Malcolm are Gretchen's two sons. They are out-of-control kids who used to wear child leashes. Once, they played throw and catch with a large sharp piece of concrete. Eventually, Malvin had to go to the emergency room to get stitches in his forehead. Malcolm is the wilder. He once got hold of Frank's shaving kit and shaved his head. He also called the police to report Greg's family for running out of ketchup. This results in Frank angrily making them leave early.

Aunt Cakey is Susan's oldest sister. She is single and has no pets or kids, suggesting that she doesn't like kids. When she stayed with the Heffleys when Greg was little, she kept all fragile items out of Greg's reach and made Greg take a nap. When she told Greg to not touch the iron, Greg can't stop thinking about it and pressed his whole hand agents the iron, giving him a second-degree burn. Susan has never trusted her with babysitting since.

Susan's cousin from California and th eldest son of Martina who lived with the Heffleys for a few months after Greg was born, which he reminds Greg of every time he sees him.

Susan's cousin who had gained a lot of money while in Las Vegas. She had been eating in a breakfast buffet in a hotel, when she mistook a full-length mirror for another room, causing Martina to run straight into the mirror, break her collarbone, and sue the hotel. Greg notes that a Porsche in Gramma's driveway was probably hers.

A man who is not actually related to anyone, but is a friend invited over one year and who has been showing up ever since. Greg likes him, but is annoyed that he always sits in Gramma's best chair until it is time to leave.

Gramma has two sisters whose names have not been confirmed yet but are suggested to be named Martha and Beatrice. They can't stand each other and try to give each other the most insulting gift they can think of.

Greg's adopted uncle who is only three or four years old. He was adopted by Great Aunt Marcie, and Greg often feels awkward around Cecil.

Greg's second cousin who has a very loose tooth that has been in her mouth for years and always stalls when people ask if they can pull it out.

Meemaw and Peepaw are the parents of Gramma and her two sisters, the maternal grandparents of Susan and the maternal great-grandparents of Rodrick, Greg and Manny. Their first appearance was in Hard Luck. Peepaw is portrayed as old and batty. Meemaw is dead, while Peepaw is still alive. Meemaw was in charge of putting prizes in the Easter eggs and wore a diamond ring, which was extremely valuable because it had been in her family for three generations. She used to overdo with hiding the Easter eggs, which results in Greg finding eggs in all sorts of strange places. As Meemaw got older, she became less sharp and started putting strange prizes in the eggs, such as a green bean, a bottle cap, and a paper clip. Before she died, she accidentally put her ring in an Easter egg that was found by Greg at the end of the book.

Meemaw appears in the film adaption of The Long Haul played by Mimi Gould. Meemaw's birthday results in Susan's "great Heffley road trip".

Mr. Jefferson is Rowley's father and is far more shrill than Mr. Heffley. He is extremely rude and paranoid and does not accept any criticism from anyone of himself or his property. He is the strictest father in the series so far. He will not let Rowley play any video game with the slightest bit of violence or fighting in it, as he thinks doing this could change Rowley into a different person. Mr. Jefferson dislikes Greg, whom he thinks is a "bad influence" on his son. After Greg and Rowley invent their own secret language, which Mr. Jefferson cracks, he sends Greg home early. It is also shown that Mr. Jefferson had a close bond with Rowley.

He shows little interest in sports until Dog Days, where he is found playing tennis with Rowley and golf with a caddy.

In Dog Days, it is revealed that Mr. Jefferson's first name is Robert. When Susan emailed him because of the note Greg sent her, it had Mr. Jefferson's first name on it.

In "Old School", he is stuck chaperoning the group of extra kids (which includes Rowley and Greg), much to Greg's dismay. Later, Rowley adds poison ivy to a fire started by him and he has problems breathing the next morning, which means he and Rowley (who had spots on his body) would be going back home.

In the film series, Mr. Jefferson has not spoken until the third film, implying that he is a man of a few words.

Mrs. Jefferson is Rowley's mother. She often seems to be concerned about Rowley, such as the time he broke his big toe after Greg put one of his dad's dumbbells under a pillow that Rowley kept kicking at Greg's sleepover.[4] She also had Greg apologize to her for what he did to Rowley. Despite this, Mrs. Jefferson always enjoys Greg's company with Rowley. Although Mrs. Jefferson loves Greg, she does not let him come over because her husband dislikes him. On day 24 of the online version, it is revealed that her first name is Linda from Greg's The Boy Whose Family Thinks He's a DOG comic.

In the film adaptations, Rowley's mother is portrayed by Kaye Capron in Diary of a Wimpy Kid (who in turn is the real-life mother of Robert Capron, the actor who plays Rowley) and by Bronwen Smith in Dog Days.

Fregley is Greg's acquaintance and neighbor noted for his many odd or disgusting eccentricities. He has been known to perplex others with his behavior and does not have any known friends. Greg has been forced to hang around with Fregley on several occasions, to his chagrin or aggravation. It has been mentioned that Fregley is prohibited from eating sugar by his parents, and the consumption of it in large quantities will send him into hysterical, uncontrollable frenzies.

After Greg inadvertently causes the Snella family to move away due to a foul smell which (unknown to the Snellas) was caused by Greg dumping deviled eggs into a plastic plant, he decides that he should find a way of sneaking deviled eggs into Fregley's house.

In the film adaptations of the books, Fregley is played by Grayson Russell.

Preston Mudd is one of Greg's classmates. He is said to have been the best player in the basketball unit of gym class during sixth grade at Westmore Middle School. Unfortunately, when his name was displayed as "P. Mudd", this led to his classmates making fun of him, calling him "Pee Mud".

Christopher Brownfield is one of Greg's friends and is shown to have been a great mosquito magnet while hanging out with Greg in the summer. However, Greg does not see him as a close friend because he is "not a school-year friend". Later in "The Ugly Truth", he is on Greg's team for a game and hides behind a soda machine after the teachers threaten to call all of their parents.

Tyson Sanders is a friend of Greg who appears in "The Ugly Truth". He is mentioned at the beginning along with Christopher when Greg is considering new best friends, and mentions that although Tyson is nice and into the same video games as Greg, he is turned off by the fact Tyson pulls his pants all the way down when using the urinal. When they play a game of "Guess Who?", the team takes a picture of Tyson's bent arm, which gets them disqualified as the chaperones think the picture is of his buttocks. However, the misunderstanding is later cleared up after a mole near Tyson's elbow is matched to one shown in the picture. Greg remarks that everyone should know what Tyson's buttocks look like due to his habit of pulling his pants all the way down when using the urinal.

Holly Hills is one of Greg's classmates; an older girl who primarily serves as Greg's unrequited romantic interest and also Heather Hills' younger sister. She is the youngest daughter of Mr. Hills and Mrs. Hills. A minor character, she earns a prominent role in The Last Straw as the object of Greg's most recent infatuation. He is continuously motivated to impress her to no avail. Virtually oblivious to Greg's existence or identity (Greg stops trying to impress her after she mistakes him for Fregley), she appears to take an interest in Rowley's sweetness, judging by an enthusiastic message which she had signed in his yearbook (as opposed to the note that she had written for the envious Greg). She seldom appears afterward. Greg's interest in her is seemingly damaged by events such as this and he starts showing an interest in other girls, including Holly's older sister Heather.

Whereas her personality is hardly explored in the books, Holly's role was increased in film adaptions, debuting in Diary of a Wimpy Kid: Rodrick Rules as a newcomer to Greg's school with whom he is instantly besotted. She is depicted as being friendly and good-natured. The relationship she shares with Greg and Rowley is emphasized and exaggerated in the film portrayals, to the extent it can be assumed that the feelings Greg has for her may be mutual. She reappears in Diary of a Wimpy Kid: Dog Days.

Holly seems to enjoy the boys' companionship and shows gratitude for Rodrick Heffley's unintentional blunders that wind up destroying the undeserving Heather's birthday party. The party ends with Holly slipping her hand into Greg's, implying that she likes him as well, and she, Greg and Rowley had a pool party not long after.

Holly is portrayed in the movies by Peyton R. List.

Chirag Gupta is an Indian American who serves as one of Greg's schoolmates and a minor character in the books. He is characterized by his short stature. Although he and Greg are well-acquainted and generally amiable to one another, Greg started the "Invisible Chirag" prank in Rodrick Rules. During the summer the Gupta family were to move away but an unexplained alteration in their plans changed this. As a result, Chirag's classmates teasingly ignore his presence for days on end, which aggravates and shocks him. Greg is called into Mr. Roy's office and is severely reprimanded, but Mr. Roy gets the identity of the victim wrong. After Greg apologises to a completely different student, who does not understand why Greg is apologising, Mr. Roy lets him go. However, after Susan gets a phone call from Chirag's father, she brings Greg to Chirag's house and orders him to apologise. Mr. Gupta is not impressed, but Chirag accepts the apology and forgives Greg.

Though Chirag has forgiven Greg and his fellow schoolmates for concocting the prank, it is mentioned in one book that he takes advantage of his family's non-observance of the Christmas holiday, and no obligation to behave for Santa Claus, to pick on Greg.

In the movie adaptions, Chirag's role is enhanced and he is a close friend of Greg and Rowley. He also plays a considerably more prominent role in these films, appearing in adaptions of books in which he is absent or hardly mentioned. He is portrayed by American actor Karan Brar, who is of Indian ancestry.

Patty Farrell is a minor character who shares an intense rivalry with Greg, which is showcased on a few occasions. It is implied she is a hardworking but sanctimonious and domineering student. She earns Greg's animosity after she suggests a map of the United States displayed in the classroom be covered during a geography quiz. Greg had planned to cheat using the map and this causes great difficulties for him, and makes him agitated. Motivated by his lust for revenge, he volunteers to play a tree in the school's upcoming production of "The Wizard of Oz"after viewing the movie adaption for the first time. He believes the role entails having to bombard the character of Dorothy Gale (whom Patty would be portraying in the play) with apples, only to learn that this scene was deleted for the school production. He winds up re-enacting this scene, despite the script, and the other trees join in. However, the play has to be shut down after Patty's glasses are broken, as Patty is short-sighted. She has yet to play quite as significant a role in the book series again. She has become something of a minor recurring character whose appearances are rare.

In the film adaptions of the books, Patty's role is enhanced slightly. She is depicted as being monstrously demanding. Her parents are involved with the school board in this portrayal. The motivation given for her hatred of Greg is his recital of an offensive playground chant poking fun at her that sent her bursting into tears in elementary school. She appears in the film adaptations of all three films Diary of a Wimpy Kid, Diary of a Wimpy Kid; Rodrick Rules and Diary of a Wimpy Kid: Dog Days. Alterations made to the books include her talent for both wrestling and playing tennis. She snatches any opportunity to assault Greg somehow while engaged in either sport with him.

She is portrayed in the movies by Laine MacNeil.

Heather Hills is the attractive elder sister of Holly Hills, with whom Rodrick is infatuated. A minor character in the books, but the main antagonist in the third film, Heather is only featured in several books as the object of Greg's unrequited infatuation. However, she seems oblivious to this. A student attending Westmore High School with Rodrick, she has had several minor occupations throughout the books, during each of which Rodrick fecklessly attempts to grab her attention or to impress her. Little insight into her personality is provided in the book series.

Heather only appears in the third movie in the film series, Dog Days wherein personality and role is further enhanced similar to her younger sister, Holly. In a modification of the events of the books, she is depicted as the spoiled, obnoxious, grouchy, ignorant, sarcastic, conceited, irritable, unforgiving, cold-hearted, and demanding oldest daughter of the Hills family who often mistreats her family and acquaintances. A lovelorn Rodrick Heffley and his band are hired to perform at Heather's ostentatious upcoming sixteenth birthday party on the suggestion by Greg himself. In an attempt to earn her admiration, Rodrick sings lead on the band's cover of Justin Bieber and Ludacris's hit song "Baby" (while his bandmate plays drums), which he claims is her favorite song, but chaos ensues when the band switches from the song's original, dance-infused pop tempo to an extremely wild, boisterous, punk rock version of the song wherein Rodrick inadvertently messes with the decorations. This angers Heather and the party ends in disaster.

She is portrayed in Dog Days by Melissa Roxburgh.

Albert Sandy is a minor character, who talks often about rumors he has heard. The validity of his statements is unconfirmed. One of the statements which were not confirmed by Greg was when Albert told him that "it was medically impossible for a girl to fart". Some make no sense, for example, he said a man got decapitated when he sneezed.

Albert has appeared in The Last Straw, The Ugly Truth, Old School, Double Down, The Meltdown, Wrecking Ball, and The Deep End.

Dennis Denard and Erick Glick are two eighth graders who run an illegal homework assignment and school project business that has them selling old projects from the school's storage room. Dennis is the ringleader while Erick acts as his public face. Dennis was also said to have been held back twice (probably on purpose so he could continue his business). In "Hard Luck", Greg attempts to buy an old science project from them, but eventually has second thoughts, thinking it would be his first step toward the life of a criminal. At the end of the book, another kid tips off a teacher, causing the faculty members to stage a raid on the storage room. Dennis, Erick, and everyone else who was caught were given detention for the rest of the school year, and Greg believes that it also includes an automatic trip to summer school.

First appearing in The Last Straw, The Snellas are a family that lives in the Heffleys' neighborhood. They have a lot of children, all of whom are male, with names beginning with the letter S. Five of the children's names are revealed, and they are (from oldest to youngest): Shawn, Shane, Sam, Scott, and Seth. In The Last Straw, it is revealed that each Snella child has a half birthday party at which the adults perform funny stunts, to attempt to make the babies laugh. According to Greg, however, no baby has laughed once.

Mr. Snella then sends the videos to America's Funniest Families, a spoof and parody of America's Funniest Home Videos, and has never won anything (though after Greg is filmed wearing Wonder Woman underwear hanging off a tree with his trousers below his ankles at the end of The Last Straw, the footage is sent, and it is never explained if Mr. Snella won with it).

Their most recent appearance was in The Ugly Truth when they move to another house because of a strange smell they cannot get rid of in their home. The smell was deviled eggs, which Greg hates and threw into one of their plant pots when he was having dinner at their house. Despite trying to find the cause of the smell, the Snellas cannot figure it out and eventually just move. Greg feels guilty when he sees that they are taking the plant pot with them, but he resolves to try to find a way to sneak deviled eggs into Fregley's house.

Scotty is a first grader from Rowley's karate class. In Rodrick Rules, Scotty was going to do a magic act in the Talent Show with Rowley as his assistant. But after Greg breaks Rowley's big toe, he has to fill in for Rowley. Greg complains about being a magician's assistant to Scotty, but Susan tells Scotty's mother that Greg would be happy to replace Rowley.

Scotty has a remarkably similar appearance to Greg's comic character, Creighton The Cretin, except Creighton's eyes are wide open and Scotty's eyes are beady just like all the other characters that do not wear glasses. In The Ugly Truth, he becomes the new Peachy Breeze kid, yet cannot say the slogan right.[7] Between Rodrick Rules and The Ugly Truth it appears that Scotty has two siblings - an unnamed baby sister and an older brother. In The Third Wheel, when Greg and Rowley become private investigators Greg looks through the window at his house to find him playing one of Greg's video games with Rowley.

In the film series, he is named Coach Malone. He is portrayed by Andrew McNee.

Bill Walter is a 35-year-old unemployed high school drop out, guitarist and professional singer, who has a rude attitude towards everyone he meets. Rodrick idolizes him and his lifestyle. In the novel Rodrick Rules, he was voted "Most Likely to Be a Rock Star" which influenced Rodrick to persuade him to join the band. Frank Heffley strongly dislikes Bill because he disapproves of his lifestyle, and is afraid Rodrick will follow in his footsteps. In the movie version of Rodrick Rules, he is portrayed by Fran Kranz and is an antagonist. He agrees to join Rodrick's rock band Loded Diper and later attempts to kick him out for an unknown reason. After performing the song Exploded Diper, Rodrick retaliates and kicks him out. In the book Greg describes him as unemployed and still living with his parents.

Dr. Kagan, Frank's dentist, makes his debut in The Ugly Truth. Frank takes Greg to Dr. Kagan instead of his usual dentist, a pretty woman named Rachel on whom Greg has a crush. Dr. Kagan has a very different approach to dentistry than Rachel. When Greg admits to drinking soda, Dr. Kagan is infuriated, and shows Greg a jar of liquid with a badly eroded tooth in it, telling him that it is a real tooth that was left in a jar of soda for 24 hours. Greg accidentally bites Dr. Kagan's finger when his teeth are being checked. In what Greg believes to be an act of revenge, Dr. Kagan tells Frank that Greg needs headgear to correct his overbite. Greg later loses his headgear, and discovers that Manny took it. He declares that he will never wear the headgear again irrespective of what Dr. Kagan says.

Greg says Dr. Kagan is scary and evil and that he never fools around. He has sharp metal tools, which he leaves on full display, and never smiles. The billboards for Dr. Kagan's dental practice make Greg freak out every time he sees one of them on the highway.

Dr. Kagan later makes a cameo in Double Down, in a scene where Greg describes how a Spineticklers book has made going to the dentist an even more frightening experience for him.

Greg and his family are convinced that the Beardos have stolen their luggage and belongings at a place they both attended called "Soak Central." They try to track them down though it was revealed at the end that Greg actually had the key to their locker in Soak Central, and that he got the number in the lottery. Their belongings were there. The family's real surname is unknown, as Greg himself does not know who they are. It is likely he dubbed them this because of the patriarch's noticeably long beard.

In the film adaption of The Long Haul, Mr. and Mrs. Beardo are portrayed by Chris Coppola and Kimberli Lincoln and have a daughter named Brandi and two sons named Brandon and Brent.

Greg buys an angelfish that was many different colors, and Rodrick buys a piranha-like fish that was said to be "aggressive". While Greg bought a journal to track everything his fish did, Rodrick neglected his fish to the point of putting its filthy bowl on top of the refrigerator and never feeding it or cleaning it once. When Greg and his family go to a waterpark, Greg's mom puts Rodrick's fish in the same bowl as Greg's fish as it was cleaner. When the Heffleys got home, Rodrick's fish had eaten Greg's, and was never referred to in the books after that.

The Heffleys’ pet pig, in the film named "Piggy", was introduced in The Long Haul, in which Manny Heffley won it at a country fair for correctly guessing the weight of a hog. In Old School and Double Down, to the annoyance of Greg, the Pig exhibits extraordinary intelligence and gains human characteristics. One running gag is that despite not having opposable thumbs, the Pig opens objects such as soda cans. In The Meltdown, the Pig throws a tantrum for being excluded from the trip to Isla de Corales in The Getaway. Frank sends it to obedience school, only for the Pig to escape on its second day there.
