Cheyenne Mountain is a triple-peaked mountain in El Paso County, Colorado, southwest of downtown Colorado Springs. The mountain serves as a host for military, communications, recreational, and residential functions. The underground operations center for the North American Aerospace Defense Command (NORAD) was built during the Cold War to monitor North American airspace for missile launches and Soviet military aircraft. Built deep within granite, it was designed to withstand the impact and fallout from a nuclear bomb. Its function broadened with the end of the Cold War, and then many of its functions were transferred to Peterson Air Force Base in 2006.

Homesteading on the mountain began in 1867 and the mountain was the site of resorts and retreats beginning in the 1880s. Spencer Penrose, who built The Broadmoor in 1918, bought many of the properties on the mountain and built the Cheyenne Mountain Zoo, Cheyenne Mountain Highway, Will Rogers Shrine of the Sun, a lodge on one of the mountain peaks, and a retreat at Emerald Valley. The site of the lodge has become a wilderness Cloud Camp and Emerald Valley is now the site of The Broadmoor's Ranch at Emerald Valley. Land on Cheyenne Mountain that had once been owned by The Broadmoor is now the site of luxury homes. A community, Overlook Colony, that began in 1911 still resides on the mountain.

The two parks on and at the base of Cheyenne Mountain are Cheyenne Mountain State Park and North Cheyenne Cañon Park. A noticeable feature on the top of one of Cheyenne Mountain's peaks is an antenna farm with transmitters for cellular phone, radio, television, and law enforcement purposes.
