The 1987–88 Seattle SuperSonics season was the 21st season of the Seattle SuperSonics in the National Basketball Association (NBA).
It was Bernie Bickerstaff's first season with a winning percentage above .500, coaching the Sonics to a 44–38 record.
However, in the 1988 NBA Playoffs, they lost in five games to the Denver Nuggets in the first round.
Xavier McDaniel was selected for the 1988 NBA All-Star Game.
Seattle selected future hall of famer Scottie Pippen in the first round thanks to a pick acquired from the New York Knicks, but traded him on draft day to the Chicago Bulls for Olden Polynice and two future conditional draft picks.
