The 1989–90 Loyola Marymount Lions men's basketball team represented Loyola Marymount University during the 1989–90 NCAA Division I men's basketball season. The Lions were led by fifth-year head coach Paul Westhead. They played their home games at Gersten Pavilion in Los Angeles, California as members of the West Coast Conference.

Powered by consensus Second-Team All-Americans Hank Gathers and Bo Kimble, LMU led the nation in scoring for the third consecutive year and established an NCAA record of 122.4 points per game. Kimble won the NCAA individual scoring title by averaging 35.3 points per game.

On March 4, 1990, Gathers collapsed and died during a WCC Tournament Semifinal matchup against Portland. The team is remembered for honoring Gathers with a run to the Elite Eight as the 11 seed in the West Region of the NCAA tournament. They would become the first WCC team to reach the Elite Eight in 33 years. The Lions defeated New Mexico State 111–92, defending National Champion Michigan 149–115, and Alabama 62–60 before falling 131–101 to UNLV, the eventual National Champion.
