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

The 1999–00 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 105th year overall where an NCAA school fielded a team.

The 1999-00 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.
