The 2026 Big Ten Conference men's ice hockey tournament was the twelfth tournament in conference history. It was played between March 11 and March 21, 2025, on-campus locations. As the tournament winner, Michigan earned the Big Ten's automatic bid to the 2026 NCAA Division I men's ice hockey tournament.
The tournament featured a format with all games taking place on the campus of the higher-seeded teams. Unlike previous editions, the quarterfinals were single-elimination, with the second, third and fourth-seeded teams each hosting a series. The top-seeded team had a bye to the single-elimination semifinals. The highest-seeded team remaining after the semifinals hosted the championship game.
