This is a season-by-season list of records compiled by St. Lawrence in men's ice hockey. St. Lawrence University has made twenty-two appearances in the NCAA Tournament, making the Frozen Four seven times and the championship game two times. Clarkson completed an undefeated season in 1956, however, because eight members of the team were 4-year seniors and would have been ineligible to play in the tournament Clarkson declined the invitation.
