The Ruby Mountains are one of the many mountain ranges of the Great Basin in the western United States. They are the most prominent range in Elko County, in the north-eastern section of the state of Nevada. To the north is Secret Pass and the East Humboldt Range, and from there the Rubies run south-southwest for about 80 miles (130 km). To the east lies Ruby Valley, and to the west lie Huntington and Lamoille Valleys. The highest peak is Ruby Dome. The Ruby Mountains are the only known range of an introduced bird, the Himalayan snowcock, in North America.

The 'Rubies' were named after the garnets found by early explorers. The central core of the range shows extensive evidence of glaciation during recent ice ages, including U-shaped canyons, moraines, hanging valleys, and steeply carved granite mountains, cliffs, and cirques. All of these features can be seen from 12-mile Lamoille Canyon Road, a National Forest Scenic Byway which traverses Lamoille Canyon, entering the range near the town of Lamoille.

Major valleys include Lamoille Canyon (and its branches Thomas and Right Fork Canyons), Seitz Canyon, Box Canyon and Kleckner Canyon. Canyons to the north drain into the main stem of the Humboldt River above Elko, while a group of canyons above the Te-Moak tribal lands constitute the headwaters of the South Fork of the Humboldt River. Major summits in the central core of the range include Ruby Dome, Thomas Peak, Liberty Peak, Mount Fitzgerald, Verdi Peaks, Snow Lake Peak, Mount Silliman, and Mount Gilbert. Prominent peaks further south include King, Wines, Tipton, and Pearl Peaks. North of the central core, significant peaks include Old-Man-of-the-Mountain and Soldier Peak.

Glaciers gouged out basins that are now alpine lakes. The larger of these, all located in the central core of the range, include Echo, Liberty, Favre, Lamoille, Castle, and Griswold lakes, while smaller tarns also in the central core include the scenic Island, Dollar, Verdi, Snow, Box, and Seitz lakes. Further to the north are Cold, Hidden, Soldier and Robinson lakes, while to the south are North Furlong and Overland lakes. Water collected by the southern section of the Rubies seeps into the adjacent Ruby Valley to form the Ruby Lake National Wildlife Refuge.
