List of Category 3 Atlantic hurricanes

Since the beginning of the Atlantic hurricane database in 1851, 162 tropical cyclones peaked at Category 3 strength on the Saffir–Simpson scale in the Atlantic basin, which covers the waters of the Atlantic Ocean north of the equator, the Caribbean Sea, and the Gulf of Mexico. Storms of such intensity have maximum sustained winds between 110–129 miles per hour (178–207 kilometres per hour). This list does not include hurricanes that intensified further to a Category 4 or 5, the latter being the highest ranking on the scale.

Collectively, Category 3 Atlantic hurricanes caused nearly $100 billion in damage. Most of the damage total was caused by Hurricane Sandy in 2012, which left $68.7 billion in damage when it struck New Jersey as a post-tropical cyclone, and which was briefly a major hurricane near Cuba.

The known Category 3 hurricanes cumulatively killed 18,361 people, including 7,469 in the 2nd half of the 19th century, 7,541 in the 20th century, and 3,351 so far in the 21st century. Four hurricanes accounted for more than half of the recorded deaths. In 1870, a hurricane killed 1,200 people in Cuba. The 1893 Sea Islands hurricane left over 1,000 casualties when it struck the U.S. state of Georgia. In 1909, a hurricane killed about 4,000 people when it moved ashore northeast Mexico. More recently, Hurricane Jeanne in 2004 killed more than 3,000 people when it moved near Haiti.
