1989 NBA playoffs

The 1989 NBA playoffs was the postseason tournament of the National Basketball Association's 1988–89 season. The tournament concluded with the Eastern Conference champion Detroit Pistons defeating the Western Conference champion Los Angeles Lakers 4 games to 0 in the NBA Finals. Joe Dumars was named NBA Finals MVP. The Pistons had one of the most dominant playoff runs in NBA history, finishing 15–2 with their only losses to the Chicago Bulls in the Eastern Conference Finals. This NBA playoffs also holds the record for the most sweeps in an entire NBA playoffs with 9 out of 15 series being decided in just 3 or 4 games.

The Lakers won the Western Conference title without losing a game, and entered the NBA Finals as the heavy favorites. However, they were swept in the Finals by the Pistons, due in part to season-ending injuries suffered by Magic Johnson and Byron Scott. The Lakers became the first team in NBA history to open an NBA post-season with 11 straight victories and to sweep three series in an NBA post-season.

Chicago advanced to the Eastern Conference Finals for the first time since 1975 (back when they were a member of the Western Conference) (and the first time in Michael Jordan's career), but their season was ended by Detroit for the second straight year. Two rounds earlier, Jordan hit "The Shot" over Craig Ehlo at the buzzer to beat the Cavs.

The Boston Celtics' first-round playoff sweep by the Pistons was the first time they failed to get past the round of 16. Boston's chances were hampered by the absence of Larry Bird during these playoffs due to a season-ending injury earlier in the season; the first and only time in Bird's NBA career he'd miss playing in the playoffs.

Former Utah Jazz head coach Jerry Sloan made the first of 19 playoff appearances in a 22-year tenure. The only time he missed the playoffs with Utah was 2004–2006. Prior to this, he had last appeared in the playoffs in 1981 with the Bulls. His Jazz were ousted by the Golden State Warriors 3–0, the second time a seventh seed had beaten the second seed in the playoffs.

This was the fifth playoff meeting between these two teams, with the Celtics winning three of the first four meetings.

This was the ninth playoff meeting between these two teams, with the 76ers winning six of the first eight meetings.

This was the second playoff meeting between these two teams, with the Bulls winning the first meeting.
