Dayton City League

The Dayton City League is an OHSAA-sponsored athletic league that is entirely made up of schools located within Dayton, Ohio that are part of Dayton Public Schools.

The league did not exist from 2002-2007 when the schools remaining after several closures and consolidations joined the Southwest Ohio Public League. Beginning in 2015 and for football only, all five football-playing schools will rejoin the SOPL.
