The Ohio League was an informal and loose association of American football clubs active between 1903 and 1919 that competed for the Ohio Independent Championship (OIC). As the name implied, its teams were based in Ohio. It is the direct predecessor to the modern National Football League (NFL). A proposal to add teams from outside Ohio, such as the Latrobe Athletic Association, to form a formal league known as the "Football Association" fell through prior to the 1904 season.
