The 1945 NFL season was the 26th regular season of the National Football League. The Pittsburgh Steelers and the Chicago Cardinals resumed their traditional operations.
The remains of the final Ohio League member Dayton Triangles, then known as the Brooklyn Tigers, and the Boston Yanks merged for this one season. The combined team, known simply as The Yanks, played four games at Boston's Fenway Park and one game at New York's Yankee Stadium. After Brooklyn Tigers owner Dan Topping announced his intentions to join the new All-America Football Conference, his rights to the Triangles' legacy franchise were immediately revoked after the season and all of its players were assigned to the Boston Yanks, who carried on the team's lineage.
The season ended when the Cleveland Rams defeated the Washington Redskins in the NFL Championship Game in Cleveland.
