The United East men's basketball tournament is the annual conference basketball championship tournament for the NCAA Division III United East Conference. The tournament has been held annually since the conference was founded in 2005 as the North Eastern Athletic Conference. The conference adopted its current name for the 2021–22 season, and underwent a major expansion in 2023 when it merged with the Colonial States Athletic Conference, with the two leagues agreeing to operate under the United East banner. It is a single-elimination tournament and seeding is based on regular season records.^[1]

The winner, declared conference champion, receives the United East's automatic bid to the NCAA Men's Division III Basketball Championship.
