Kaycee is a town in Johnson County, Wyoming in the USA. The population was 249 at the 2000 census. It is home to a museum that preserves the cattle ranching heritage of the area, especially the history of the Johnson County War.
Western music star and rodeo champion Chris LeDoux (1948–2005) resided on a ranch near Kaycee, although he was actually born in Biloxi, Mississippi.
Kaycee was incorporated in 1906 after the establishment of a small post office and general store. The town was named after the brand "KC" used by its earliest homesteader, John Nolan. The government required the name to be spelled out resulting in "Kaycee". The town is now home to three churches, two bars, one restaurant, one store, one museum, one k-12 school, and not a single stoplight. (www.kayceewyoming.org)
