The 1993 Big West Conference men's basketball tournament was held March 12–14 at the Long Beach Arena in Long Beach, California.
The 49ers subsequently received an automatic bid to the 1993 NCAA tournament.
Regular-season champions, and tournament runners-up, New Mexico State received an at-large bid.
Nevada, in their first year as Big West members (moving from the Big Sky), failed to qualify for the tournament.
The Wolf Pack replaced outgoing Fresno State, who left to join the WAC.
