List of sister cities in Colorado

Monument in Pueblo dedicated to its sister city of Chihuahua

This is a list of sister cities of cities and towns in the United States state of Colorado . 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 Colorado jurisdictions work with foreign cities through Sister Cities International, an organization whose goal is to "promote peace through mutual respect, understanding, and cooperation." ^[1]
