The 1990–91 NBA season was the Detroit Pistons' 43rd season in the National Basketball Association, and 34th season in the city of Detroit. The Pistons entered the season as both the three-time defending Eastern Conference Champions the two-time defending NBA Champions and looked to win a third consecutive title. The team posted a nine-game winning streak in November as they finished the first month of the season with a 13–2 record. However, they would lose six of their next seven games in early December, but held a 34–15 record at the All-Star break. Midway through the season, the Pistons won eleven consecutive games, finishing second in the Central Division with a 50–32 record, eleven games behind the Chicago Bulls.
