The 1986 NBA Finals was the championship round of the National Basketball Association (NBA)'s 1985–86 season, and the culmination of the season's playoffs. It pitted the Eastern Conference champion Boston Celtics against the Western Conference champion Houston Rockets, in a rematch of the 1981 NBA Finals (though only Allen Leavell and Robert Reid remained from the Rockets' 1981 team). It was the second and last NBA Championship Series of the 1980s not to feature the Los Angeles Lakers, who were eliminated by the Rockets on both occasions.
