Wild Horse is an unincorporated village in Cheyenne County, Colorado, United States. The community takes its name from Wild Horse Creek, and began in 1869 as a cavalry outpost, which soon became a railway station and had expanded to a town by the mid-1870s. After a peak of population and business activities in the early 1900s, the town began dwindling by 1917, when most of it burned down in a great fire. The town rebuilt, but never at the population or business-service centralization level of its earlier years, and by the 1930s, had begun to dwindle further.
There is still a post office at Wild Horse, which has been in operation since 1904. and currently services Zip Code 80862. There is also a one-room school house, no longer in use, and a cluster of older small homes.
