1999–2000 NCAA Division I men's ice hockey season

The 1999–2000 NCAA Division I men's ice hockey season began on October 1, 1999, and concluded with the 2000 NCAA Division I Men's Ice Hockey Tournament's championship game on April 8, 2000, at the Providence Civic Center in Providence, Rhode Island. This was the 53rd season in which an NCAA ice hockey championship was held and is the 106th year overall where an NCAA school fielded a team.

The 1999–2000 season was the inaugural year for College Hockey America, a seven-team conference (Wayne State begins conference play the following year) that was created for the purpose of stabilizing all the remaining independent Division I ice hockey teams.

The University of Vermont cancelled the remainder of their season on January 14, 2000, as a result of a criminal investigation into hazing practices when it was revealed that players had lied to investigators.
