Allegheny County, Home rule county in southwestern Pennsylvania, United States.
Allegheny County is a home rule county in southwestern Pennsylvania that incorporates urban centers and residential neighborhoods across varied terrain. The region sits within the Pittsburgh metropolitan area and includes both densely populated and more rural sections.
The county was established in September 1788 as one of Pennsylvania's original counties. It transformed from agricultural land into a major industrial center during the 1800s.
The region is home to respected universities like Carnegie Mellon and the University of Pittsburgh that shape local education and community life. Their presence brings students, events, and cultural activities that influence how people in the area live and interact.
Pittsburgh International Airport provides direct flights to destinations across North America and Europe, making the region accessible by air. Plan for variable transportation options and travel times when moving between different parts of the county.
Three rivers meet within the county: the Allegheny, Monongahela, and Ohio. This geographic feature has shaped local development and how people have moved goods and traveled through the region.
