The 1920 Canton Bulldogs season was the franchise's sixteenth and its first in the American Professional Football Association (APFA), which became the National Football League two years later. Jim Thorpe, the APFA's president, was Canton's coach and a back who played on the team. The Bulldogs entered the season coming off a 9–0–1 performance as Ohio League champions in 1919. The team opened the season with a 48–0 victory over the Pitcairn Quakers, and finished with a 7–4–2 record, taking eighth place in the 14-team APFA. A then-record crowd of 17,000 fans watched Canton's week 12 game against Union AA of Phoenixville.
