2024 Big Ten men's basketball tournament

The 2024 Big Ten men's basketball tournament (branded as the 2024 TIAA Big Ten Men's Basketball Tournament for sponsorship reasons) was a postseason men's basketball tournament for the Big Ten Conference of the 2023–24 NCAA Division I men's basketball season which took place from March 13–17, 2024. The tournament was held at the Target Center in Minneapolis, Minnesota. This was the first year in which the first round is broadcast by Peacock. As the tournament winner, Illinois received the conference's automatic bid to the 2024 NCAA Division I men's basketball tournament.

This was the last season in the current tournament format as the conference will expand to 18 teams the following year. The conference announced that only 15 teams will participate in future tournaments with the bottom three teams not qualifying for the tournament.

Seeds
All 14 Big Ten schools are participating 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.
