The 1989 NCAA Division I men's basketball tournament involved 64 schools playing in single-elimination play to determine the national champion of men's NCAA Division I college basketball. It began on March 16, 1989, and ended with the championship game on April 3 in Seattle. A total of 63 games were played.

Michigan, coached by Steve Fisher, won the national title with an 80–79 overtime victory in the final game over Seton Hall, coached by P. J. Carlesimo. Glen Rice of Michigan set an NCAA tournament record by scoring 184 points in six games and was named the tournament's Most Outstanding Player.

Just prior to the start of this tournament, Michigan coach Bill Frieder had announced that he would accept the head coaching position at Arizona State University at the end of the season. Michigan athletic director Bo Schembechler promptly fired Frieder and appointed top assistant Fisher as interim coach, stating famously, that "a Michigan man is going to coach a Michigan team."

Two 16-seeded teams came within one point of victory in the first round (Georgetown vs. Princeton, Oklahoma vs. East Tennessee State), and a third came within six points. This tournament was also unusual in that all four 11-seeds advanced out of the first round.

The 1989 Tournament was the second one since 1980, with 1987 being the first, in which the defending national champion did not participate in the tournament. Kansas, winner of the 1988 NCAA title, had been placed on probation for violations committed by former coach Larry Brown and was barred from the tournament. Brown left Kansas immediately after winning the national championship to return to coaching in the NBA with the San Antonio Spurs, leaving first-year coach Roy Williams to coach the team. It is the only time the Jayhawks have missed the NCAA tournament from 1984 to the present day. The defending champion would not be left out of the next year's tournament again until 2008. The tournament was notable for the poor performance of the SEC. After traditional stalwart Kentucky missed the postseason after experiencing its first losing season since 1927, none of the five SEC teams won a game in the tournament.
