The Mogollon Mountains or Mogollon Range (/mʌɡᵻˈjoʊn/ or /moʊɡəˈjoʊn/) are a mountain range in Grant County and Catron County of southwestern New Mexico, in the Southwestern United States. They are primarily protected within the Gila National Forest.
The Mogollon Mountains range is located west of the Gila River and east of the San Francisco River, between the communities of Reserve and Silver City. They extend roughly north-south for about 30 miles (48 km), and form part of the divide between the San Francisco and Gila Rivers. The crest of the range lies about 15 miles (24 km) east of U.S. Route 180, which traverses parallel to a section of the San Francisco River. The Sierra Aguilada, a lower altitude smaller range, borders to the west of Route 180. Most of the Mogollon Mountains range is protected within the Gila Wilderness, in the Gila National Forest.
