1981 NBA Finals

The 1981 NBA World Championship Series was the championship round of the National Basketball Association (NBA)'s 1980–81 season, and the culmination of the season's playoffs. It pitted the 62–20 Eastern Conference champion Boston Celtics against the 40–42 Western Conference champion Houston Rockets. The Celtics defeated the Rockets in six games for their fourteenth NBA championship. This series has the distinction of featuring for the third time in NBA history, and last to date, a team with a losing record in the Finals. They were the first team since the Minneapolis Lakers in 1959 to reach the championship round despite having more regular season losses than wins. This, along with 1986 (which was also played by the Celtics and the Rockets), was one of the only two NBA Finals of the 1980s not to feature the Lakers. As of 2026, this is the last time the Celtics won the NBA championship on the road.
