The 1977–78 NCAA Division II men's ice hockey season began in November 1977 and concluded on March 18 of the following year.
The NCAA instituted a Division II national championship beginning with this season.
Due to the number of independent programs and the lack of any conference tournament for western teams, the NCAA also began holding a playoff series for western teams to help determine which schools would receive bids.
Because all teams were still members of ECAC 2 and the larger conference began holding two tournaments, doubled the number of participants beginning with this season, no NYCHA tournament was ever held.
