Great Northern Conference

The Great Northern Conference is a high school athletic conference in the Wisconsin Interscholastic Athletic Association. It comprises seven teams from Marathon, Taylor, Lincoln, Oneida, Langlade and Vilas counties in Northern Wisconsin. The Conference was formed in 2008 with former Lumberjack members Lakeland, Medford, Northland Pines and Tomahawk, Cloverbelt member Mosinee, and Wisconsin Valley's Antigo and Merrill. In 2010, Merrill returned to the Wisconsin Valley conference and Rhinelander took its place. In December 2023 Merrill had filed a request within the WIAA Conference Realignment process to move the school back to the Great Northern Conference. Merrill has cited declining enrollment as its top reason.
