# 2020–21 Boston Celtics season

The 2020–21 Boston Celtics season was the Celtics' 75th season in the National Basketball Association (NBA). As a result of the COVID-19 pandemic, the regular season for the league began on December 22, 2020, and featured a 72-game schedule rather than the typical 82-game schedule. The Celtics finished the regular season with a 36–36 record, and clinched a playoff spot after defeating the Washington Wizards with a score of 118–100 in the play-in tournament.
In the opening round of the playoffs, the Celtics were defeated by the Brooklyn Nets in five games, marking the first time the Celtics were eliminated in the first round since 2016. Following the season, Danny Ainge left his position as general manager, and named head coach Brad Stevens as his replacement.
