The 2020–21 Alaska Nanooks men's ice hockey season would have been the 72nd season of play for the program, the 37th at the Division I level and the 8th in the WCHA conference.

Due to health concerns as a result of the ongoing COVID-19 pandemic, Alaska notified the WCHA on December 11, shortly before it was scheduled to begin its season, that the university had decided to suspend its program for the season.

[1] The NCAA had previously announced that all winter sports athletes would retain whatever eligibility they possessed through at least the following year.

[2] Less than a week after Alaska's announcement, the NCAA approved a change in its transfer regulations that would allow players to transfer and play immediately rather than having to sit out a season, as the rules previously required.

[3] Because of this, players who would have been members of Alaska for the 2021 season had a pathway to leave the program and immediately play for another university.
