The 2020-21 American International Yellow Jackets men's ice hockey season was the 73rd season of play for the program, the 25th at the Division I level, and the 18th season in the Atlantic Hockey conference. The Yellow Jackets represented American International College and were coached by Eric Lang, in his 5th season. The start of the college hockey season was delayed due to the ongoing coronavirus pandemic. As a result, American International's first scheduled game was in late-November as opposed to early-October, which was the norm.
