List of sister cities in Pennsylvania

This is a list of sister states, regions, and cities in the U.S. state of Pennsylvania. Sister cities, known in Europe as town twins, are municipalities (sometimes counties, regions, states and other sub-national entities) that cooperate to foster cultural links. They interact with each other across a broad range of activities, often including education, business, the arts, or health care.^[1]

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."^[2]
