The 2018 Big Ten Conference Men's Ice Hockey Tournament was the fifth tournament in conference history. It was played between March 2 and March 17, 2018, on campus locations.[1] The winner of the tournament was the Notre Dame Fighting Irish, who earned the Big Ten's automatic bid to the 2018 NCAA Division I Men's Ice Hockey Tournament.
The 2018 tournament featured a new three-weekend format with all games taking place on the campus of the higher-seeded teams. The tournament opened March 2–4 with three best-of-three quarterfinal series, as the second-, third-and fourth-seeded teams each hosted a series. The top-seeded team had a bye to the single-elimination semifinals, which was played on March 10. The highest-seeded team remaining after the semifinals hosted a championship game on March 17.[2]
