The 1994 Big West Conference men's basketball tournament was held March 10–13 at the Thomas & Mack Center in Paradise, Nevada.
Top-seeded New Mexico State defeated UC Irvine (the tournament's lowest-seeded team, with only 4 conference wins) in the final, 70–64, to capture their second PCAA/Big West title.
The Aggies subsequently received an automatic bid to the 1994 NCAA tournament.
The Big West returned to a ten-team tournament with all conference members in participation.
As a result of the field's expansion, this was the first tournament for second-year Big West member Nevada.
