NCAA Division I men's ice hockey tournament

The annual NCAA Division I Men's Ice Hockey Tournament is a college ice hockey tournament that is held in the United States by the National Collegiate Athletic Association (NCAA) to determine the top men's team in Division I. Like other Division I championships, it is also the highest level of NCAA men's hockey competition. This tournament is also somewhat unique among NCAA sports as many schools which compete in Division II or Division III in other sports will compete in Division I for hockey.
