The 1989–90 NBA season was the Bulls' 24th season in the National Basketball Association. Despite their solid playoff run last year, the Bulls fired head coach Doug Collins and replaced him with Phil Jackson. Under Jackson, the Bulls finished the regular season with a 55–27 record, averaging 109.5 points per game and being led by Michael Jordan's league-leading 33.6 ppg. Clinching second place in the Central Division and a third seed in the playoffs, the Bulls defeated the Milwaukee Bucks three games to one in the first round, then defeated the Philadelphia 76ers four games to one in the semifinals. They advanced to the Eastern Conference Finals before losing a seven-game series to the eventual champion Detroit Pistons.

On March 28, 1990, Jordan scored a career-high 69 points against the Cleveland Cavaliers, the highest scoring output by an NBA player since David Thompson's 73 points on April 9, 1978, against the Detroit Pistons. Scottie Pippen made his first All-Star appearance as he was selected for the 1990 NBA All-Star Game along with Jordan.
