1998–99 NCAA Division I men's ice hockey season

The 1998–99 NCAA Division I men's ice hockey season began on October 3, 1998 and concluded with the 1999 NCAA Division I Men's Ice Hockey Tournament's championship game on April 3, 1999 at the Arrowhead Pond of Anaheim in Anaheim, California. This was the 52nd season in which an NCAA ice hockey championship was held and is the 104th year overall where an NCAA school fielded a team.

The 1998-99 season was the inaugural year for Metro Atlantic Athletic Conference's hockey division. Because only Canisius, Fairfield, and Iona were full members of the MAAC, five additional associate members were included to make the conference viable. All five teams had been part of ECAC lower classifications in the past (as had Canisius, Fairfield and Iona) and were promoted to Division I for the 1998-99 season.
