The 1921 Chicago Staleys season was their second regular season completed in the young American Professional Football Association (APFA), later known as the National Football League. All games were played at home, with the team opening the year in Decatur, Illinois before moving to Chicago in time for its second league game.

The team improved on their 10–1–2 record from 1920 to a 9–1–1 record under head coach/player George Halas earning them a first-place finish in the team standings and their first league championship — the best finish of the initial Halas era.

At the end of the season, team Secretary Morgan O'Brien was appointed as the vice-president of the APFA.
