The 2020–21 Canisius Golden Griffins men's ice hockey season was the 41st season of play for the program, the 23rd at the Division I level, and the 18th season in the Atlantic Hockey conference. The Golden Griffins represented Canisius College and were coached by Trevor Large, in his 4th season. The start of the college hockey season was delayed due to the ongoing coronavirus pandemic. As a result, Canisius's first scheduled game was in late-November as opposed to early-October, which was the norm.
