1981 NCAA Division I men's ice hockey tournament

It was held between March 19 and 27, 1981, and concluded with Wisconsin defeating Minnesota 6-3.

1981 was the first year that the tournament guaranteed 8 teams to be selected for the championship as opposed the policy put in place in 1977 that gave the selection committee the ability to choose up to 4 additional teams at its discretion (two was the maximum the committee ever choose).

The NCAA permitted 8 teams to qualify for the tournament, four from each region (East and West).

From the west the two WCHA tournament co-champions and the CCHA tournament champion received automatic bids with a fourth at-large bid going to one western team.

Beginning with the Semifinals all games were played at the Duluth Arena and all series became Single-game eliminations.
