# 2023 Big West Conference men's basketball tournament

The 2023 Big West Conference men's basketball tournament was the postseason men's basketball tournament for the Big West Conference of the 2022–23 NCAA Division I men's basketball season. It was held March 7–11, 2023, at the Dollar Loan Center in Henderson, Nevada. The winner, the UC Santa Barbara Gauchos, received the conference's automatic bid to the 2023 NCAA tournament.

## Seeds

Of the 11 conference teams, 10 were eligible for the tournament. UC San Diego was ineligible for the tournament, as it was in the third year of the four-year transition required for teams transferring to Division I from Division II. Teams were seeded based on their performance within the conference, and teams with identical conference records were seeded using a tiebreaker system. Unlike previous years before 2020, teams were no longer reseeded before the semifinals.
