The 1975 Pittsburgh Pirates season was the 94th in the history of the franchise and their 89th in the National League.
The Pirates' 92–69 record was good enough to win their fifth National League East title in six seasons by 61⁄2 games over their cross-state rivals, the Philadelphia Phillies.
The Pirates, however, lost the NLCS to the Cincinnati Reds, three games to none.
