Ruby Valley is a large basin located in south-central Elko and northern White Pine counties in the northeastern section of the state of Nevada in the western United States. From Secret Pass it runs south-southwest for approximately 60 miles (96 km) to Overland Pass. To the west is the steep escarpment of the Ruby Mountains, and to the north is the East Humboldt Range and Clover Valley. The east side of the valley is less well defined, but its maximum width is about 10 miles (16 km) near Franklin Lake. At its south end lies the Ruby Lake National Wildlife Refuge.
SR 229 passes along the northeast edge of the valley, and Ruby Valley Road (SR 767 and CR 788) runs along its western edge. Harrison Pass Road (CR 718) crosses the Ruby Mountains near the center of the valley. Much of the floor of Ruby Valley lies at elevations near 6000 feet (1820 m).
The valley played an important role in the history of the Great Basin. Nomadic tribes of the Shoshone nation used Ruby Valley as a winter home, finding it warmer than nearby locations. The California Trail, active after the 1840s, was located just to the north. The Donner Party passed through the southern end of the valley in 1846, heading for the Overland Pass route across the Ruby Mountains – part of the Hastings Cutoff.
