The 2013 Great West Conference Men's Basketball Tournament was held March 14–16, 2013, in Chicago, Illinois at the Emil and Patricia Jones Convocation Center. Per NCAA regulations as a new Division I conference, the Great West champion would not have received an automatic bid into the NCAA Tournament until 2020. The winner, however, did receive an automatic bid to the CollegeInsider.com Tournament. This was the final GMC men's basketball tournament as the conference dissolved after the season due to its member schools joining other conferences.
