The 1939 Pittsburgh Pirates season was the franchise's seventh season as a professional football club in the National Football League (NFL). The Pirates brought John McNally back for his third year, however, after finishing with a 2–9 record, Owner Art Rooney provided him with support by signing Walt Kiesling during the offseason. Despite this, the Pirates experienced their worst season yet, placing last in the league with a 1–9–1 record. The team just barely tallied a number in the win column, but during Week 11, they beat the Philadelphia Eagles. It was their first win at home in 9 games at Forbes Field (Week 10, 1937). It was also the final season for the franchise before becoming the "Steelers" the following season.
