The 1941 Green Bay Packers season was their 21st season in the National Football League. The club posted a 10-1 record under coach Curly Lambeau, earning a tie for first place in the Western Conference with the Chicago Bears. The Packers and Bears played a one-game playoff in Chicago to determine who would play in the NFL Championship Game. The Packers lost 33-14 to the Bears, in the first post-season game ever played between the archrivals. The second post-season game came 70 years later, in the NFC Conference Championship game on January 22, 2011.
