The following is a listing of all 30 current National Basketball Association (NBA) teams ranked by win–loss record percentage, accurate as of the end of the 2020–21 NBA regular season. The records include wins and losses recorded by a team's playing time in the Basketball Association of America (BAA).[a] Defunct BAA/NBA franchises are also listed, provided they played at least one season, beginning with the 1949–50 NBA season, which was the first season following the merger between the BAA and the National Basketball League (NBL).[b] Additionally, the records do not count wins and losses recorded by a team's playing time in the American Basketball Association (ABA), despite the 1976 ABA–NBA merger.
The San Antonio Spurs have the highest win–loss record percentage, with 2,227–1,394 (.615). The Minnesota Timberwolves have the lowest win–loss record percentage, with 1,003–1,545 (.394). The Boston Celtics have recorded the most wins, with 3,462; the Sacramento Kings have recorded the most losses with 3,135. The Boston Celtics lead the association with the most played games, with 5,868. Conversely, the Pelicans have played the least overall games, with 1,522.
After the regular season, 12 teams (the top 6 seeds per conference) automatically clinch a playoff berth. Meanwhile, the 7th through 10th seeds in both conferences enter in a Play-in Tournament to determine both conferences' final two playoff seeds. Through the end of the 2021 Play-In Tournament, the Memphis Grizzlies have played the most Play-in games (3) and recorded the most Play-in wins (2). The Golden State Warriors have conversely recorded the most Play-in losses (2), and have the lowest win–loss percentage with 0–2 (.000). The Charlotte Hornets and San Antonio Spurs also have a win percentage of .000, but have played only one game each. The Boston Celtics, Los Angeles Lakers, and Portland Trail Blazers are all tied for the highest win–loss percentage in the Play-in Tournament at 1–0 (1.000).
As of the end of the Conference Semifinals of the 2021 NBA playoffs, the Los Angeles Lakers have the most post-season games played (761), wins (456), and losses (305), as well as the highest post-season winning percentage with 456–305 (.599) of any NBA team. The Minnesota Timberwolves have the fewest post-season wins (18) and the lowest post-season winning percentage with 18–34 (.346). The New Orleans Pelicans have the fewest post-season games played (49).

The NBA introduced a Play-in Tournament in the 2019–20 NBA season to compensate for the suspension of the regular season and a difference in the amount of games played between teams, as a result of the COVID-19 pandemic. For the 2019–20 season, if a conference's 9th seed was within 4 games of the 8th seed in the standings, a play-in scenario between the two seeds would be triggered. The 8th seed would need to win one game, while the 9th seed would need to win two in the matchup. Ultimately, the Western Conference's Portland Trail Blazers and Memphis Grizzlies would face off in a Play-in game.
Due to a combination of the success of the Play-in tournament and the COVID-19 pandemic persisting into the NBA's 2020–21 season, the league installed a Play-in tournament involving both conference's 7th- through 10th-placed teams in the regular season standings. The format of the Play-in tournament involves the 7th-place team playing the 8th-place team with the winner clinching the 7th seed in the playoffs. The 9th-place team plays the 10th-place team with the loser being eliminated from playoff contention. The loser of the 7th-8th matchup will then play the winner of the 9th-10th matchup, with the winner clinching the 8th seed and the loser being eliminated.
The following list is accurate through the end of the 2021 Play-in Tournament games.

- For the purposes of this list, NBL statistics are not included, as unlike with BAA statistics prior to the BAA-NBL merger, the NBA has not included NBL statistics when recapping their history.
- The Lakers played in Minneapolis from 1948–1960.
- The Utah Jazz played in New Orleans from 1974–1979.
