Ohio Athletic Conference

The Ohio Athletic Conference (OAC) was formed in 1902 and is the third oldest athletic conference in the United States. Its current commissioner is Sarah Otey. Former commissioners include Mike Cleary, who was the first General Manager of a professional basketball team to hire an African American head coach, and would later run the National Association of Collegiate Directors of Athletics (NACDA). It is an intercollegiate athletic conference which competes in the NCAA's Division III. Through the years, 31 schools have been members of the OAC. The enrollments of the current ten member institutions range from around 1,000 to 4,500. Member teams are located in Ohio.

History
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, 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.
