Northeast Ohio Conference

The Northeast Ohio Conference (NOC) was a high school athletics conference, recognized by the Ohio High School Athletic Association (OHSAA), in northeast Ohio. Eighteen member schools — each located within the Northeast District of the OHSAA (Class AAA, Divisions I and II) — competed in three six-member divisions: Valley, River and Lake. Dan Gerome served as the last NOC commissioner. Anthony J. Paletta designed the conference logo in 2006.
