The 2020 Patriot League men's basketball tournament was the postseason tournament for the Patriot League during the 2019âÂÂ20 NCAA Division I men's basketball season. It was held on March 3, 5, 8, and 11, with the higher seed in each match up hosting at their respective campus sites. No. 3 seed Boston University defeated Colgate 64âÂÂ61 in the championship game to win the conference tournament championship and the conference's automatic bid to the 2020 NCAA Division I men's basketball tournament. The NCAA Tournament would be subsequently canceled in order to mitigate the spread of COVID-19. The Patriot League was the final conference to hold its championship game before all others remaining were cancelled due to the COVID-19 pandemic.
The Patriot League Tournament Championship was Boston University's first since joining the conference in 2013.
All 10 Patriot League teams are eligible for the tournament. The top six teams receive a first round bye. Teams are seeded by record within the conference, with a tiebreaker system to seed teams with identical conference records.
