Hot Springs County–Thermopolis Municipal Airport is a general aviation airport 10 miles northwest of Thermopolis, Wyoming. The airport was opened in 2015 to replace the original Thermopolis Municipal Airport, which was in the city of Thermopolis, but was unsuitable to expand.

The original Thermopolis Airport was located adjacent to the northwest side of the town, and now serves as part of the Thermopolis Golf Course. The earliest depiction of the original Thermopolis Airport was on the June 1936 Cheyenne Sectional Chart. It depicted Thermopolis Airport as a commercial/municipal airport.
