About: List of state and county courthouses in Pennsylvania

This is a list of former and current non-federal courthouses in the Commonwealth of Pennsylvania. Each of the 67 counties in the Commonwealth has a city or borough designated as the county seat where the county government resides, including a county courthouse for the court of general jurisdiction, the Court of Common Pleas. Other courthouses are used by the three state-wide appellate courts (the Supreme Court, the Superior Court, and the Commonwealth Court), or minor courts such as the municipal courts of Philadelphia and Pittsburgh, or magisterial district courts. As noted below, some courthouses are listed on the National Register of Historic Places.
