Thermopolis is the county seat and most populous town in Hot Springs County, Wyoming, United States. As of the 2020 census, Thermopolis had a population of 2,725.

Thermopolis, Greek for "hot city", is the location of numerous natural hot springs, in which mineral-laden waters are heated by geothermal processes.
