1921–22 Harvard Crimson men's ice hockey season

The 1921–22 Harvard Crimson men's ice hockey season was the 24th season of play for the program.

Season
Before the season, Harvard finally accepted the trend of all other college teams and agreed to play 6-on-6 hockey for the year. Additionally, Harvard accepted the new practice of playing its two defenders side by sire rather than one in front of the other. The changes did little to hamper the Crimson in their first game, however, when they returned from their Christmas break the team had to quickly prepare for Toronto. The Blues were considered by many as the top amateur team in North America and they demonstrated why when they dominated Harvard to the tune of a 6–1 victory. Harvard was able to get much more practice time before their next game and when they faced Dalhousie they appeared much more themselves.

The Crimson didn't lose another game after the Toronto debacle, though they did tie two amateur clubs in the middle of their season. After wrapping up the Triangular League championship, Harvard put together an informal group of players, composed of members of both the varsity and freshman teams, and played an exhibition match with Boston College. The cross-town rivals won the game in overtime, but Harvard was missing both its starting goaltender and team captain, so there was little doubt as to which varsity squad was the better.
