2015 Big Ten men's basketball tournament

This was the eighteenth annual Big Ten tournament and was the first tournament to feature 14 teams of the expanded Big Ten to include Maryland and Rutgers.

As a result, Wisconsin received the Big Ten's automatic bid to the NCAA tournament.

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.

Seeding for the tournament was determined at the close of the regular conference season.
