1921–22 RPI Engineers men's ice hockey season

The 1921–22 RPI Engineers men's ice hockey season was the 19th season of play for the program. The team was coached by Leroy Clark in his 5th season.

Season
Rensselaer began its season with a road game at Williams. While both teams had to contend with rough ice, the Ephs played as a team while the Engineers acted as if they were by themselves. The contrast in styles led to an easy win for the home team as RPI was unable to handle the attack from the Purple squad. Captain Tierney was the only one to score the Rensselaer in the otherwise terrible game.

The second match a few weeks later provided RPI with its best opportunity for a win. Unfortunately, a total lack of offense prevented the Engineers from earning a win. In their only home game of the year, Rensselaer played a fast game against YMCA College. The team's minimal attack was stopped by a sturdy defensive effort from the Maroons and the single goal from the visitors was all they needed. RPI had an extended break until their next game due to the exam break but the team didn't appear any better when they met YMCA for a rematch. The offense remained silent in the match and, though the still only allowed one goal, the Engineers lost once more.

Afterwards, the team headed south to play Columbia. While the Lions had the advantage of experience with avoiding the pillars that were set into the surface of their home rink, the disparity in play was even more stark as Columbia easily won the game. Tierney was again the only player on the scoresheet for Rensselaer. The team played its final game of the year the following week and they were completely outclassed by Hamilton. Playing at the brand new Russell Sage Rink, Hamilton lit the lamp 12 times while Rensselaer was unable to get any offense going. The loss finished off possibly the worst season in program history.
