Carson is a small census-designated place in Skamania County in the southwestern part of the U.S. state of Washington.
Carson is located just north of the Columbia River near the towns of Stevenson, Bingen and White Salmon in Washington and Cascade Locks and Hood River in Oregon and just south of Stabler, Washington. One major point of interest is the St. Martin's hot spring and resort, boasting a geothermal steam bath.
A post office called Carson has been in operation since 1894. The community takes its name from nearby Carson Creek.
