Rankings from AP poll

The 1989 Pacific-10 Conference men's basketball tournament was played March 9–12 at the Great Western Forum in Inglewood, California. Like the previous year, both top seeds advanced to the final; Stanford made its first appearance in the title game and met the top-seeded (and top-ranked) Wildcats. Comfortably repeating as champion of the tournament was Arizona, which received the Pac-10's automatic bid to the NCAA tournament. Repeating as the Most Outstanding Player was Sean Elliott of Arizona.

This was the tournament's third edition and all ten teams participated.
