The 2012 Big West Conference men's basketball tournament took place March 8–10, 2012 at the Honda Center in Anaheim, California.[1] The Tournament was previously held at the Anaheim Convention Center. Long Beach State won the tournament, which allowed them to receive the conference's automatic bid to the 2012 NCAA Division I men's basketball tournament. Cal State Northridge was banned from competing in postseason play for failing to meet the NCAA's Academic Progress Rate requirements.[2]
Eight teams qualified for the 2012 Big West tournament. In the semifinals the highest seed will play the lowest seed, while the remaining two teams match up.
