The 1989–90 NBA season was the Bucks' 22nd season in the National Basketball Association. For the first time since the 1978–79 season, Sidney Moncrief was not on the team's opening day roster. During the off-season, the Bucks acquired All-Star guard Alvin Robertson and Greg Anderson from the San Antonio Spurs. Early into the season, the Bucks defeated the Seattle SuperSonics in a quintuple-overtime game on November 9, 155–154 at the Bradley Center. The team held a 27–22 record at the All-Star break. At midseason, the team traded Randy Breuer to the expansion Minnesota Timberwolves in exchange for Brad Lohaus. The Bucks finished third in the Central Division with a 44–38 record.
