The 1933 NFL season was the 14th regular season of the National Football League. Because of the success of the 1932 NFL Playoff Game, the league divided its teams into two divisions for the first time, with the winners of each division playing in a championship game to determine the NFL champion. Three new teams also joined the league: the Pittsburgh Pirates, the Philadelphia Eagles, and the Cincinnati Reds. Also, the Boston Braves changed its name to Boston Redskins and Staten Island Stapletons resigned.
