The Minnesota–North Dakota ice hockey rivalry is an intercollegiate ice hockey rivalry between the Minnesota Golden Gophers and North Dakota Fighting Hawks. The rivalry is between two of the most successful programs in the sport, as the teams have combined for 13 national titles and 43 Frozen Four appearances in the NCAA tournament.

In 2005, the programs would meet in the Frozen Four for the second time. North Dakota raced to a 4–0 lead and held on despite two late goals from the Gophers.
