Plum is often referred to as "Plum Boro" or more correctly "Plum Borough" by locals to distinguish it from its previous status as a township. It was founded as Plum Township in 1788 and was reorganized as a borough in 1956. The borough took its name from nearby Plum Creek.
Allegheny County was formed on September 24, 1788. Allegheny County was originally made up of seven townships, plus the then borough of Pittsburgh. Plum was one of those original seven townships. Originally extending as far south as Versailles (modern-day North Versailles Township), east to the county line, west to Penn Township, and north to the Allegheny River, Plum Township was founded on December 18, 1788. Plum has shrunk greatly over the years in area, but still remains among the larger municipalities in Allegheny County.
