The 1993 Pittsburgh Pirates season was the 112th in franchise history; the 107th in the National League. This was their 24th season at Three Rivers Stadium. This season saw the three-time defending National League East champions fall to 5th place in the division with a 75–87 record. In the offseason, the National League expanded to 14 teams and Barry Bonds left the Pirates and signed with the San Francisco Giants. This season was the first of the Pirates record setting twenty straight losing seasons.
