The Washita River is a river in the states of Texas and Oklahoma in the United States. The river is 295 miles (475 km) long and terminates at its confluence with the Red River, which is now part of Lake Texoma (33°55′N 96°35′W / 33.917°N 96.583°W) on the Texas–Oklahoma border.
The Washita River forms in eastern Roberts County, Texas (35°38′N 100°36′W / 35.633°N 100.600°W), near the town of Miami in the Texas Panhandle. The river crosses Hemphill County, Texas and enters Oklahoma in Roger Mills County. It cuts through the Oklahoma counties of Roger Mills, Custer, Washita, Caddo, Grady, Garvin, Murray, Carter, and Johnston before emptying into Lake Texoma, which is the modern border between Bryan County and Marshall County.
