Mount Oliver is a borough in Allegheny County, Pennsylvania, United States. It is a largely residential area situated atop a crest about 3 miles (5 km) west of the Monongahela River. The borough is surrounded entirely by the city of Pittsburgh, having resisted annexations by the city, as it prefers to manage its own local needs and finances.[1]

It is named for Oliver Ormsby, son of John Ormsby, who held the original land grant for the area from George III. Mount Oliver has experienced some tough times of late which are associated with the slippage of the steel-making capacity of the Pittsburgh region. The population was 3,403 at the 2010 census.[2]


Mount Oliver is located at 40°24′41″N 79°59′12″W / 40.41139°N 79.98667°W / 40.41139; -79.98667 (40.411319, -79.986571).[3]

According to the United States Census Bureau, the borough has a total area of 0.3 square miles (0.9 km²), all of it land.

Mount Oliver is completely surrounded by the city of Pittsburgh. The borough's business district runs across the length of the neighborhood, from the South Side Slopes to Carrick. Brownsville Road runs along this ridge, and connects South Eighteenth Street in Pittsburgh with the neighborhood of Carrick and communities further east. Mount Oliver Borough borders the neighborhood of Mount Oliver in Pittsburgh.

Mount Oliver Economic Development Team[edit]

This organization formed in recent years to address the needs of this business community. Maria DiSimone Praczak, a local artist, has donated her time and talent to beautifying the empty storefronts as they await new occupants. The murals she has created can be observed in several storefront display windows.
