The Colorado State Archives has custody of the incorporation records for most cities and towns covering the period 1871 through 1977. The more recent municipal incorporation records are housed at the Office of the Secretary of State. While these records are inherently important to the historical foundation of our State, they also can provide the researcher with genealogical and legal documentation. Municipal incorporation records may have plat and city plan maps as well as charters. Occasionally codes and ordinances, court transcripts, and annexation documentation exist. Furthermore, these records may include voting records and poll books, which provide the names of those living in the prospective city and its founding citizens.
Below is a list of the incorporated cities and towns in Colorado. Included in this list is the municipality's county location and its incorporation date.
The information below primarily comes from the Colorado Gazetteer of
Cities and Towns, published by the Colorado State Planning Division for
inclusion in the Colorado Year Book, 1958. For
incorporations after 1958, the information comes from The
Directory of Municipal and County Officials in Colorado 1999-2000, published
by the Colorado Municipal League, 1999. Address all
documented corrections, additions, and
comments to the Colorado State Archives.
