The Eastern Ohio Athletic Conference (EOAC) is an Ohio High School Athletic Association high school athletic conference that began competition in the 2017âÂÂ18 school year and is made up of member schools from Columbiana and Mahoning counties in Ohio. The league was formed from members of the red and white tiers of the former Inter-Tri County League.
The Eastern Ohio Athletic Conference was formed when the Inter-Tri County League disbanded in 2016. Seven members of the red and white tiers of the ITCL would form the EOAC (Columbiana, Lisbon, East Palestine, Leetonia, Southern, Toronto, United and Wellsville.) conference play began in the fall 2017âÂÂ18 season.
Toronto announced they would forfeit its membership in the EOAC after two seasons of membership. They left following the 2018âÂÂ19 school year, citing different reasons for their departure such as financial reasons from higher league and official costs, and lower crowds of both home and away games due to traveling distance between member schools. Toronto had rejoined its previous conference, the Ohio Valley Athletic Conference.
Youngstown Valley Christian accepted its invitation to join the EOAC in 2019, with them beginning conference play in the 2020âÂÂ21 school year. They were previously a member of the Portage Trail Conference but left due to wanting to compete with schools closer to enrollment size and travel distance.
Leetonia, who is one of the EOAC's founding members, announced in 2025 they will be departing from the league following the 2025âÂÂ26 school year, with them joining the Northeastern Athletic Conference in hopes of playing schools closer in size and competition to them.
