The 1975 Green Bay Packers season was their 57th season overall and their 55th season in the National Football League. Under new head coach Bart Starr, they finished at 4–10, last in the four-team NFC Central division.
The Packers opened with four losses, then beat the Super Bowl-bound Dallas Cowboys on the road for Starr's first coaching win. After a 1–8 start, Green Bay ended the season on a positive note, winning three of their final five games.
In week 5, the Packers defeated the Dallas Cowboys on the road, improving their all-time record to 8–1 over the Cowboys; the sole loss was in 1970. Dallas was the eventual NFC champion and advanced to Super Bowl X.
