1920–21 RPI men's ice hockey season

The 1920–21 RPI men's ice hockey season was the 18th season of play for the program. The team was coached by Leroy Clark in his 4th season.

Season
As was typical for the program, the Cherries played a scant number of games and didn't perform particularly well. RPI's offense was sorely lacking in most of their games and caused the team to be non competitive in three losses. The lone win for the team came against the worst team in college hockey, New York State, though even there Rensselaer didn't have very good news. Despite the win, RPI scored 17 fewer goals than they had the year before and only won due to the paucity of talent available to their opponents.

Note: Rensselaer's athletic teams were unofficially known as 'Cherry and White' until 1921 when the Engineers moniker debuted for the men's basketball team.
