Eldorado Valley, or El Dorado Valley, is a Great Basin valley in the Mojave Desert southeast of Las Vegas and southwest of Boulder City, Nevada. The valley is endorheic, containing the Eldorado Dry Lake. The Great Basin Divide, transects ridgelines and saddles, on the north, northeast, east, and south around the valley, as the valley sits on the east of the McCullough Range, a Great Basin massif, on the Great Basin Divide at its north terminus and its south terminus. Much of the valley is protected as part of Avi Kwa Ame National Monument.
