This is a list of sister cities in the United States state of Pennsylvania. Sister cities, known in Europe as twin towns, are cities which partner with each other to promote human contact and cultural links, although this partnering is not limited to cities and often includes counties, regions, states and other sub-national entities.
Many Pennsylvania jurisdictions work with foreign cities through Sister Cities International, an organization whose goal is to "promote peace through mutual respect, understanding, and cooperation."
