The Pittsfield Red Sox was the name of an American minor league baseball franchise based in Pittsfield, Massachusetts, from 1965 through 1969. It was the Double-A Eastern League affiliate in the Boston Red Sox farm system and produced future Major League Baseball players such as George Scott, Sparky Lyle, Reggie Smith and Hall of Famer Carlton Fisk. The team played at Wahconah Park.
The Berkshire city fielded its first team in Organized Baseball in 1894 when the Pittsfield Colts debuted in the New York State League, but the Colts folded after 30 games. After the Pittsfield Electrics played two seasons (1913–1914) in the Class B Eastern Association, which folded after the 1914 campaign, Pittsfield was first represented in the Eastern League (then Class A) in 1919–1920 as the Hillies, and won the 1919 EL pennant.
Pittsfield then fielded a team in the Class C Canadian–American League from 1941 through 1951 (although the league suspended operations for 1943–1945 due to World War II). This club, initially nicknamed the Electrics, was affiliated with the Detroit Tigers (1942), Cleveland Indians (1946–1950) and Philadelphia Phillies (1951). After 1948, it dropped the Electrics identity and was named after its parent club.
