The 1938 Green Bay Packers season was their 20th season overall and their 18th season in the National Football League. The team finished with an 8–3 record in 1938 under head coach Curly Lambeau, earning them a first-place finish in the Western Division. In the championship game at the Polo Grounds, the Packers lost to the New York Giants 23–17, the first of only three losses the Packers have in 13 world championship games. The two teams met again in the title game the following year at Wisconsin State Fair Park, with different results.
