The 2019 NCAA Men's Division I Ice Hockey Tournament was the national championship tournament for men's college ice hockey in the United States. The tournament involved 16 teams in single-elimination play to determine the national champion at the Division I level of the National Collegiate Athletic Association, the highest level of competition in college hockey. The tournament's Frozen Four – the semifinals and finals – were hosted by the MAAC at the KeyBank Center in Buffalo, New York from April 11-13, 2019. This was the second Frozen Four in the city of Buffalo, as it previously hosted in 2003. This was the first championship since 2007 to have multiple programs make their first NCAA tournament appearance. Bowling Green State University made their first appearance in the NCAA tournament in 29 years. While for the first time since 1992 an Independent program made the tournament. Unfortunately, the tournament is as remembered for the lack of attendance as anything that happened on the ice. All semifinal and championship games had at least 5,000 fewer spectators than the building capacity and the title game saw the lowest attendance since 2000. Though there was much discussion on the matter, a general consensus by fan bases was that the ticket prices of $200-$300 was far too high even for a championship game.
