Locations of members in the Ohio Athletic Conference

The Ohio Athletic Conference was found in 1902 with six charter members—Case Tech, Kenyon, Oberlin, Ohio State, Ohio Wesleyan, and Western Reserve. By 1934, the conference reached an all-time high of twenty-four members, ^[1] seeing many schools come and go throughout the upcoming decades. By 2000, the conference solidified to its current form with the addition of its final school, Wilmington, to ten members.

On January 18, 2024, John Carroll University announces departure from the OAC to the North Coast Athletic Conference (NCAC), beginning in the 2025–26 academic year. ^[2]
