Pennsylvania (; Pennsylvania German: Pennsilfaani), officially the Commonwealth of Pennsylvania, is a state spanning the Mid-Atlantic, Northeastern, Appalachian, and Great Lakes regions of the United States. It borders Delaware to the southeast, Maryland to the south, West Virginia to the southwest, Ohio to the west, Lake Erie and the Canadian province of Ontario to the northwest, New York to the north, and the Delaware River and New Jersey to the east.

Pennsylvania is the fifth-most populous state in the nation with over 13 million residents as of 2020. It is the 33rd-largest state by area and ranks ninth among all states in population density. Nearly 4.29 million residents are concentrated in the southeastern Delaware Valley metropolitan area, centered around Philadelphia, the state’s largest and nation’s sixth most populous city. Another 2.37 million reside in Greater Pittsburgh in the southwest, centered around Pittsburgh, the state’s second-largest and Western Pennsylvania’s largest city. The state’s subsequent five most populous cities are Allentown, Erie, Reading, Bethlehem, and Scranton. The state capital is Harrisburg.

Pennsylvania’s geography is highly diverse: the Appalachian Mountains run through the center of the state; the Allegheny and Pocono mountains span much of Northeast Pennsylvania; close to 60% of the state is forested. While it has only 140 miles (225 km) of waterfront along Lake Erie and the Delaware River, Pennsylvania has more navigable rivers than any other state in the nation, including the Delaware, Ohio, and Pine Creek rivers.

Pennsylvania was founded in 1681 through a royal land grant to William Penn, son of the state’s namesake; the southeast portion was once part of the colony of New Sweden. Established as a haven for religious and political tolerance, the Province of Pennsylvania was known for its relatively peaceful relations with native tribes, innovative government system, and religious pluralism. Pennsylvania was one of the thirteen British colonies from which the nation ultimately was formed.
