The 2018 Big Ten men's basketball tournament was the postseason men's basketball tournament for the Big Ten Conference of the 2017âÂÂ18 NCAA Division I men's basketball season. It was held from February 28 through March 4, 2018 at Madison Square Garden in New York City. Due to the Big East's use of that venue for their conference tournament, the Big Ten tournament took place one week earlier than usual, ending the week before Selection Sunday.
Michigan defeated Purdue in the championship game to win their second consecutive tournament championship. As a result, they received the conference's automatic bid to the NCAA tournament.
The tournament was the second Big Ten Conference tournament held outside the conference's traditional heartland in the Midwest following the 2017 tournament held at the Verizon Center in Washington, D.C.
All 14 Big Ten schools participated in the tournament. Teams were seeded by conference record, with a tiebreaker system used to seed teams with identical conference records. The top 10 teams received a first round bye and the top four teams received a double bye. Tiebreaking procedures remained unchanged from the 2017 Tournament.
