Edgar Peak is a 7,162-foot-elevation (2,183-meter) summit in San Bernardino County, California, United States.

Topographic relief is significant as the summit rises 3,160 feet (963 meters) above the surrounding terrain in 1.5 miles (2.4 km).

An ascent of the summit involves 4.2 miles of strenuous off-trail hiking with 3,000 feet of elevation gain, best done in cooler months from October through May.

The rhyolite cuts across and intrudes adjacent sedimentary units and is interpreted to represent the feeder system of an extrusive dome.
