1923 NFL season

The 1923 NFL season was the 4th regular season of the National Football League. For the first time, all of the clubs that were considered to be part of the NFL fielded teams. The new teams that entered the league included the Duluth Kelleys, the St. Louis All Stars (which only lasted one season), and a new Cleveland Indians team. The Evansville Crimson Giants folded from the league.

The Canton Bulldogs repeated as NFL Champions after ending the season with an 11–0–1 record.
