The Mountain Empire is a rural area in southeastern San Diego County, California. The Mountain Empire subregion consists of the backcountry communities in southeastern San Diego County. The area is also sometimes considered part of the East County region of San Diego County.
The Mountain Empire occupies the largely hilly, rugged terrain of the Laguna Mountains and foothills between Interstate 8 and the U.S.-Mexico border east of Otay Mountain and west of Imperial County. Communities located just north of Interstate 8, such as Descanso, Guatay and Pine Valley, are generally included within the region, while those further north, such as Julian, are not. The Pacific Crest Trail has its southern terminus on the Mexican border near Campo. Portions of the Mountain Empire are located in the Descanso Ranger District of the Cleveland National Forest.
California State Route 94 and Interstate 8 are the primary highways through the region. Historic U.S. Route 80 also passes through the Mountain Empire, as does the now disused San Diego and Arizona Eastern Railway.
