List of National Basketball Association longest winning streaks

This is a list of the longest winning streaks in National Basketball Association (NBA) history. The list includes streaks that started at the end of one season and carried over into the following season. There are two lists, streaks that consist entirely of regular-season games and streaks made up of playoff games only. The Los Angeles Lakers hold the record for the longest winning streak in NBA history. They won 33 straight games in the 1971–72 season, compiling a season-best 69–13 record and went on to win the NBA Finals. In the 2016–17 season, the Golden State Warriors posted a season-best 67–15 regular-season record and began the 2017 playoffs with a 15 game win-streak, the most consecutive wins in NBA playoff history. They went on to win the NBA Championship with a 16–1 (.941 winning percentage) record, the best playoff record in NBA history.

The Los Angeles Lakers appear six times across both lists, with four streaks over 15 games in the regular-season and two over ten games in the postseason. The Boston Celtics appear five times, with all five streaks in the regular-season. The San Antonio Spurs appear four times, with two streaks in the regular-season and two in the postseason.
