List of all-time NFL win–loss records

The National Football League (NFL) is a professional American football league, which as of the end of its 2020 season, consists of 32 teams. These teams are divided equally between the National Football Conference (NFC) and the American Football Conference (AFC), and both conferences contain four divisions with four teams each. Since its formation in 1920, as the American Professional Football Association (APFA), NFL game results have been recorded. Games in the NFL can either end with a winner and a loser, or the two teams can tie. Ties are registered as a half-win and a half-loss when calculating the win–loss percentage.

One of only two charter members of the NFL still in existence,[1] the Chicago Bears have played the most games (1,384) and recorded both the most wins (777) and ties (42) in NFL regular season history, as of the end of the 2020 NFL season.[2] Their NFC North divisional rival Green Bay Packers hold the highest regular season win–loss percentage (.569), with a 769–577–38 record through the end of the 2020 season.[3] The league's other still-active charter member, the Arizona Cardinals have recorded the most regular season losses (771), through the end of the 2020 season.[4] The Tampa Bay Buccaneers maintain the lowest regular season win–loss percentage (.393), holding a 278–429–1 record, through 2020.[5] Being the most-recently founded franchise in the NFL, the Houston Texans have recorded the fewest games played (304), wins (135), and losses (169); together with the Jacksonville Jaguars, they are the only teams yet to record a tie, as of the end of the 2020 NFL season.[6][7]

Following the regular season, teams that won their respective divisions, in addition to three wild card teams determined by a conference's next best three teams—regardless of division—qualify for the league's postseason, called the playoffs.[lower-alpha 2] Ties cannot occur in the playoffs. The Dallas Cowboys have played in the most playoff games (63), through the end of the Conference Championship round of the 2020–21 NFL playoffs. The New England Patriots have the most playoff wins (37) and the highest playoff win–loss percentage (.638), with a 37–21 record, as of the end of the Conference Championship round of the 2020–21 NFL playoffs. The Minnesota Vikings have recorded the most playoff losses (30), whereas the Cincinnati Bengals have the lowest playoff win–loss percentage (.263) with a 5–14 record. The Houston Texans have the fewest games played (10), wins (4), and losses (6) in NFL playoff history.

When combining regular season and playoff win–loss records, the Bears hold the distinction for most overall games played (1,455), whereas the Packers have recorded the most wins (805) and the highest winning percentage (.571), with a 805–601–38 record through the end of the 2020 NFC Championship game. The Cardinals have recorded the most losses (780), and the Buccaneers hold the lowest winning percentage (.396), with a 287–438–1 record through the end of the 2020 NFC Championship game.

The NFL officially counts and includes the statistical records logged by teams that played in the American Football League (AFL) as part of NFL history. Therefore, these teams' pre-merger win–loss records are accounted for. However, the NFL does not officially count All-America Football Conference statistics, despite the 1950 NFL–AAFC merger.[8][lower-alpha 3]
