1920–21 MIT Engineers men's ice hockey season

The 1920–21 MIT Engineers men's ice hockey season was the 20th season of play for the program. The Engineers were coached by Chippy Gaw in his 1st season.

Season
Before the season, MIT was able to secure Chippy Gaw, a professional baseball player, as the team's head coach. The team had trouble getting into shape as there was high demand for the ice at the Boston Arena. The lack of practice caused the team to stumble out of the gate and lose its first two games by an identical 3–4 score. In the second Boston College game, Nickle made nearly 50 saves to secure an overtime win.

After a late goal game them a win over Amherst, the team faced its oldest foe in Harvard at the Arena. While Dan MacNeil scored a pair of goals to bookend the first intermission, the Engineers could not stand up to the crimson onslaught and surrendered 8 goals in the match. The following match provided a surprising victory for Tech when they took down Dartmouth. The win gave the Engineers a chance at a winning record with just 1 game to play. The rubber match with BC would serve as the finale for the season. Unfortunately, the game did not go in Tech's favor. playing with 6-man teams, rather than the 7-aside the Engineers were used to, Tech looked lost in the game and were easily beaten by the hill-toppers.
