The 2026 Big Ten men's basketball tournament (branded as the 2026 TIAA Big Ten Men's Basketball Tournament for sponsorship reasons) was a postseason men's basketball tournament for the Big Ten Conference in the 2025âÂÂ26 NCAA Division I men's basketball season. The tournament took place from March 10âÂÂ15, 2026 at the United Center in Chicago, Illinois. As the tournament winner, Purdue received the conference's automatic bid to the 2026 NCAA tournament.
On September 18, 2025, the Big Ten announced that the tournament would expand to include all 18 teams. In the previous edition, the first since the conference expanded to 18 teams, only the top 15 teams qualified for the tournament.
With a win over Illinois on February 27, 2026, Michigan clinched the number one seed in the tournament.
Teams were seeded by conference record, with a tiebreaker system used to seed teams with identical conference records.
