The 1915 Canton Bulldogs season was their sixth season that the Canton Bulldogs franchise competed in the Ohio League, a professional American footballsports league. For the first time since 1906, that the team was once again called the "Bulldogs". The season also marked the arrival of the legendary Jim Thorpe to the Canton lineup. The team finished with a known record of 5–2 and a share of the Ohio League title with the Massillon Tigers and the Youngstown Patricians.
This was Jim Thorpe's first professional football game. He was used sparingly by coach Harry Hazlett. Hazlett was shortly thereafter fired by manager Jack Cusack for benching Thorpe, which Cusack felt may have cost Canton the game.
