The 2020–21 Holy Cross Crusaders men's ice hockey season was the 57th season of play for the program, the 23rd at the Division I level, and the 18th season in the Atlantic Hockey conference. The Crusaders represented the College of the Holy Cross and were coached by David Berard, in his 7th season. The start of the college hockey season was delayed due to the ongoing coronavirus pandemic. As a result, Holy Cross's first scheduled game was in mid-November as opposed to early-October, which was the norm.
