The NCAA Men's Ice Hockey Championship refers to one of two championships in men's ice hockey contested by the National Collegiate Athletic Association (NCAA) since 1971 to determine the top team in the NCAA Division I and Division III. The NCAA Division II Men's Ice Hockey Championship was held from 1978 to 1984 and from 1993 to 1999, but it was discontinued due to a lack of Division II conferences sponsoring ice hockey.
The semi-finals and finals are branded as the "Frozen Four", echoing the NCAA Division I Men's Basketball Tournament's "Final Four". The final two rounds of the hockey tournament were first referred to as the Frozen Four in 1999.
The NCAA started a Women's Frozen Four beginning with the 2000-01 season.
