Chemult is an unincorporated community in Klamath County, Oregon, United States, on U.S. Route 97 near the drainage divide between the Klamath and Columbia Rivers. Chemult has a population of about 300 people. Chemult’s elevation is 4,764 feet.

The locale was originally established in 1924 as a station on the Southern Pacific Cascade Line named “Knott” during construction. The station’s name was changed to Chemult when the line opened in 1926 and a post office was established the same year. The name Chemult comes from a Klamath chief who was one of the 26 who signed the Klamath Lake Treaty of October 14, 1864.
