1973–74 NCAA Division I men's ice hockey season

The 1973–74 NCAA Division I men's ice hockey season began in October 1973 and concluded with the 1974 NCAA Division I Men's Ice Hockey Tournament's championship game on March 16, 1974, at the Boston Garden in Boston, Massachusetts. This was the 27th season in which an NCAA ice hockey championship was held and is the 80th year overall where an NCAA school fielded a team.

In the summer of 1973 the NCAA changed the classifications of the tiers in each of their sponsored sports. The university- and College-divisions were done away with and replaced by numerical designations making this the first official Division I season.

The NIT held a competing ice hockey tournament for the first time. The tournament included NAIA champion Lake Superior State, ECAC 2 champion Vermont and two NCAA Division I schools (Minnesota–Duluth and Saint Louis). Minnesota–Duluth won the championship but the tournament was not renewed for a second season.
