The 1989 West Coast Athletic Conference men's basketball tournament was held March 4–6 at War Memorial Gymnasium on the campus of the University of San Francisco in San Francisco, California. This was the third edition of the tournament and the last as the WCAC; the conference name was shortened to "West Coast Conference" (WCC) that summer.

The fourth-seed and host Dons lost in the quarterfinals and the top two seeds were defeated in the semifinals. Third-seeded Loyola Marymount defeated #5 seed Santa Clara 75–70 (in overtime) in the title game to repeat as WCAC tournament champions.

The Lions earned the automatic bid to the 64-team NCAA tournament and were seeded twelfth in the Midwest regional. Regular-season champion Saint Mary's received an at-large bid and were the eighth seed in the West regional; both WCAC teams lost in the first round.
