The 1911 college football season was the last one before major reforms were made to the American game in 1912. In 1911, touchdowns were worth five points, the field was 110 yards in length, and a team had three downs within which to advance the ball ten yards. The United States Naval Academy (Navy) finished with a record of 6 wins and 3 ties (6–0–3). Two of the ties were 0–0 games with the other major unbeaten teams, Penn State (8–0–1) and Princeton (8–0–2). Other teams that finished the season unbeaten were Minnesota (6–0–1) and Florida (5–0–1). The Helms Athletic Foundation, founded in 1936, declared retroactively that Princeton had been the best team of 1911

The 1911 Florida Gators football team represented the University of Florida during the 1911 college football season. The season was George Pyle's third as the head coach of the University of Florida football team. The University of Florida adopted the "Florida Gators" nickname for its sports teams in 1911; the earlier Florida football teams were known simply as "Florida" or the "Orange and Blue." Pyle's newly christened Florida Gators finished their sixth varsity football season 5–0–1—the first, and to date, the only undefeated season in the history of the Florida Gators football program.
