The Spring Mountains are a mountain range of Southern Nevada in the United States, running generally northwest–southeast along the west side of Las Vegas and south to the border with California. Most land in the mountains is owned by the United States Forest Service and the Bureau of Land Management and managed as the Spring Mountains National Recreation Area within the Humboldt-Toiyabe National Forest and the Red Rock Canyon National Conservation Area.
