List of all-time NBA win–loss records
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 2021–22 NBA regular season. The records include wins and losses recorded by a team's playing time in the Basketball Association of America (BAA). 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). 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 2,261–1,442 (). The Minnesota Timberwolves have the lowest win–loss record percentage, with 1,049–1,581 ().
