The 2000 NCAA Division III Men's Ice Hockey Tournament was the culmination of the 1999–00 season, the 17th such tournament in NCAA history. It concluded with Norwich defeating St. Thomas in the championship game 2-1. All Quarterfinals matchups were held at home team venues, while all succeeding games were played in Superior, Wisconsin.
The NCAA began offering automatic bids to conference tournament champions for the first time. Seven of the eight existing conferences received automatic bids with only the MCHA not included. This was because the MCHA had a Division II program who participated in their conference tournament; both ECAC East and ECAC Northeast had Division II members as well but none of those team participated in their respective conference tournaments. This allowed the results to be certified as Division III.
With the NESCAC now sponsoring ice hockey as a sport and holding an individual conference tournament, the conference rules limiting member schools to only one postseason tournament were dropped.
Despite being in Division III since 1973, ECAC Northeast received its first entry into the national tournament.
