Great Northern Conference
The Great Northern Conference is a high school athletic conference based in north central Wisconsin. Founded in 2008, the conference and its member schools belong to the Wisconsin Interscholastic Athletic Association.
History
The Great Northern Conference was formed in 2008 by seven medium-sized high schools in north central Wisconsin. Four of its original members were previously members of the Lumberjack Conference, which had disbanded the year prior. Two schools joined from the Wisconsin Valley Conference and Mosinee moved over from the Cloverbelt Conference. For Antigo and Merrill, this move grouped them with schools more in line with their enrollment size instead of being two of the smallest schools in their former conference. Two years after the Great Northern Conference was formed, Merrill swapped affiliations with Wisconsin Valley Conference member Rhinelander. They rejoined in 2025 from the Wisconsin Valley Conference, bringing the Great Northern Conference's membership group to eight schools.List of member schools
