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.[4]


Plum Township was founded on December 18, 1788 as one of the original seven townships of Allegheny County. It originally extended as far south as Versailles (modern-day North Versailles Township), east to the county line, west to Pitt Township, and north to the Allegheny River. Plum has shrunk greatly over the years in area, but still remains among the larger municipalities in Allegheny County.[5]


According to the United States Census Bureau, the borough has a total area of 29.0 square miles (75 km2), of which 28.6 square miles (74 km2) is land and 0.4 square miles (1.0 km2), or 1.34%, is water. Plum Borough is the second largest borough (area-wise) in the state of Pennsylvania.[6]
