The Principals Athletic Conference (PAC-8) is an Ohio High School Athletic Association (OHSAA) athletic league, formed in 1989, made up of seven schools from Stark, Summit, and Wayne counties with full membership, and one football-only member in Ashland County.
The PAC-8 (the PAC-7 prior to 2007) is home to some of the biggest rivalries in high school sports: The Triway Titans vs. the Orrville Red Riders, the Fairless Falcons vs. Tuslaw Mustangs in "The Blue Cup", and Manchester Panthers vs. Tusky Valley in the battle for the "Red, White, and Black".
