The 1923 NFL season was the fourth regular season of the National Football League (NFL). It was the second year after the name of the league was changed from the original "American Professional Football Association."

For the first time, all of the clubs that were considered to be part of the NFL fielded teams. The new clubs that entered the league included the Duluth Kelleys, the St. Louis All Stars (which only lasted one season), and a new Cleveland Indians team, while the Evansville Crimson Giants dropped out of the league and folded.

The Canton Bulldogs repeated as NFL Champions after ending the season with an 11–0–1 record. No championship game took place; rather the title was decided based upon winning percentage for games played with other National League teams.
