1985–86 Boston Celtics season

The 1985–86 Boston Celtics season was the 40th season of the Boston Celtics in the National Basketball Association (NBA). They finished with the best record in the league at 67–15, including a 40–1 record at home. Those 40 home wins set an NBA record which would only be matched by the San Antonio Spurs in 2016. Arguably considered the best Celtics team ever, and widely regarded among the greatest teams in NBA history, their 67 total wins were one win shy of tying their franchise record of 68 wins set in 1973, and tied for fifth all-time.
