The West Walker River is a tributary of the Walker River, approximately 95 miles (153 km) long, in eastern California and western Nevada in the United States. It drains part of the Sierra Nevada range along the California-Nevada border in the watershed of Walker Lake in the Great Basin.
It rises from snowmelt in the Sierras of northwestern Mono County, north of Yosemite National Park approximately 20 miles (32 km) SSW of Walker in the Emigrant Wilderness. It flows north, along the west side of the Sweetwater Mountains, emerging into the Antelope Valley, a ranching region around Walker. It flows north past Coleville and Topaz and enters southern Douglas County, Nevada southwest of Carson City. In Nevada it flows northeast, joining the East Walker River from the west 7 mi (11.3 km) south of Yerington to form the Walker River.
The river is heavily used for irrigation in the ranching valleys along its lower course. Its waters are diverted along its upper course to form Topaz Lake along the California-Nevada border. It receives the Little Walker River from the south near its source in the mountains.
