Plum is a borough in Allegheny County in the U.S. state of Pennsylvania. A suburb of Pittsburgh, Pennsylvania, it is located northeast of the city of Pittsburgh, in what is commonly referred to as the East Hills suburbs. The population was 27,126 at the 2010 census.
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 Allegheny County was originally made up of seven townships, plus the then borough of Pittsburgh.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.
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.

The Plum Borough School District serves the borough grades K–12. The elementary schools (grades K–6) are Center, Holiday Park, Regency Park, and Pivik. A.E. OBlock Junior High School serves grades 7–8 and Plum Senior High School serves grades 9–12. There were once two other elementary schools, one called Renton Elementary School, and the other called Adlai E. Stevenson, both have since been torn down. Adlai is currently (as of the 2012-13 school year) being replaced with a new building which will be a replacement for Holiday Park Elementary, the original of which will then close. During construction, students who formerly went to Adlai were sent to the old Pivik Elementary location, which [Pivik] moved to a new location for the 2011-2012 school year. Once the new Holiday Park opens in Fall 2015, students who would have attended the old Holiday Park and former Adlai will attend it. Current enrollment figure totals for the 2014/15 school year for all k-12 are 3890. The current school board said they would build a new school for the Regency kids but voted no to the act 34 so they are in the old Holiday Park.
Plum Borough is also serviced by the Plum Borough Community Library. The library houses the history room of the Allegheny Foothills Historical Society (the Historical Society also provides tours of the reconstructed Carpenter Family Log House in Boyce Park).
