At the time of the 2020 census, Cheyenne County was one of the least densely populated Colorado counties, with a population of 1,748. This is only around one person per square mile.
The county is named after the Cheyenne Indians who occupied eastern Colorado, and the county seat is Cheyenne Wells. Now a historical museum, the Old Cheyenne County Jail in Cheyenne Wells is listed on the National Register of Historic Places. Built in 1894 and used as a jail until 1961, the structure was designed by Colorado architect Robert Roeschlaub.
