Men's Division I is a set of schools and conferences that sponsor men's hockey and abide by the National Collegiate Athletic Association's rules and regulations for Division I ice hockey. There are currently five conferences that sponsor Division I hockey:
- Atlantic Hockey
- Central Collegiate Hockey Association
- ECAC Hockey
- Hockey East
- Western Collegiate Hockey Association
These five conferences represent all but one of the 58 teams that compete at the Division I level in men's hockey. The Alabama-Huntsville Chargers are Division I Independents. Division I represents the highest possible level of investment in hockey, and also the highest level of competition. If a school is a Division I institution, they must compete at the Division I level in all sports. However, schools are allowed to "play up" in one sport, and several Division II and Division III schools choose to "play up" to Division I hockey.
