The Superior 100 Mile Trail Race is an annual ultramarathon in Minnesota. The race starts at Gooseberry Falls State Park and runs along the Superior Hiking Trail until it finishes at Caribou Highlands Lodge on Lutsen Mountains. It is run on the first Friday and Saturday in September.

Having started in 1991, the Superior 100 Mile Trail Race is the ninth oldest 100 mile trail race in the United States. It has a reputation for being among the most difficult races of its kind, owing to grueling climbs and unpredictable weather conditions.
The race has of vertical climbs and in 2013 the average finish time was 34 hours. The Superior 100 has a time limit of 38 hours.
The course records after the 2023 race are held by Neal Collick (18:56:02) for men and Gretchen Metsa (21:54:10) for women.
The current course has been run since 2006, which was originally measured twice via a surveying wheel by Donald Clark and Bonnie Riley. The original course ran from the junior high school in Silver Bay, Minnesota to the Cook County football field in Grand Marais, Minnesota on the Superior Hiking Trail. Harry Sloan, race director from 1991 to 1997 along with Tami Tanski-Sherman, believes the current course is more challenging than the original.
