The 1931 Green Bay Packers season was their 13th season overall and their 11th in the National Football League.
The team finished with a 12–2 record under coach Curly Lambeau, earning them a first-place finish and the Packers' third consecutive National Football League Championship.
The Packers became the first team to win three consecutive NFL championships.
They would later do it again, wining the 1965 NFL Championship Game as well as Super Bowl I and Super Bowl II.
They remain, as of the 2023 season, the only team to accomplish this feat.
