Clinton is a city in Custer and Washita counties in the U.S. state of Oklahoma. The population was 9,033 at the 2010 census.
The community began in 1899 when two men, J.L. Avant and E.E. Blake, decided to locate a town in the Washita River Valley.
Because of governmental stipulations that an Indian could sell no more than one half of a 160-acre (0.6 km2) allotment, the men made plans to purchase 320 acres (1.3 km2) from four different Indians - Hays, Shoe-Boy, Nowahy, and Night Killer - and paid them each $2,000 for 80 acres (320,000 m2) to begin the small settlement of Washita Junction.
