The Cardinal Conference was a high school athletic conference in north central Ohio that existed from 1960 to 1987. With its dissolution, several teams joined the Ohio Heartland Conference. In 2003, a new conference, the Ohio Cardinal Conference, was formed with the expressed intention of preserving the legacy of the original Cardinal Conference.
