The Red Rock Canyon National Conservation Area in Clark County, Nevada, is an area managed by the Bureau of Land Management as part of its National Landscape Conservation System, and protected as a National Conservation Area. It is about 15 miles (24 km) west of Las Vegas, and is easily seen from the Las Vegas Strip. More than two million people visit the area each year.

The conservation area showcases a set of large red rock formations: a set of sandstone peaks and walls called the Keystone Thrust. The walls are up to 3,000 feet (910 m) high, making them a popular hiking and rock climbing destination. The highest point is La Madre Mountain, at 8,154 feet (2,485 m).

A one-way loop road, 13 miles (21 km) long, provides vehicle access to many of the features in the area. Several side roads and parking areas allow access to many of the area trails. A visitor center is at the start of the loop road. The loop road is also popular for bicycle touring; it begins with a moderate climb, then is mostly downhill or flat.

Red Rock Canyon is a side-canyon accessible only by an unmaintained primitive road from the scenic loop which mostly only off-road or high clearance vehicles can access. State Route 159 cuts through an unnamed but often-visited valley; it is commonly, but mistakenly, referred to as Red Rock Canyon. The Wilson Cliffs, or Keystone Thrust, a massive wall of rock, can be seen to the west from SR 159.

Toward the southern end of the National Conservation Area are Spring Mountain Ranch State Park; Bonnie Springs Ranch, which includes a replica of a western ghost town; and the village of Blue Diamond.
