Keyesville (formerly, Keysville[1] and Hogeye[2]) is an unincorporated community in Kern County, California.

[1] It is located 2 miles (3.2 km) west of Lake Isabella and the Kern River Valley, at an elevation of 2,848 feet (868 m).

Among the more famous visitors to Keyesville was Grizzly Adams and the "Shootin' Walkers", a family of gunslingers who took up residence here and built the Walker Cabin just outside of the Keyesville townsite, which still stands today.

A petition to the commander of Camp Babbitt about the depredations of the local Native Americans led to the Keyesville Massacre nearby on 19 April 1863.

[4] A number of wildflowers are in evidence in this part of the Greenhorn Mountains, including the yellow mariposa lily, Calochortus luteus, which species is at the southern limit of its range within the Greenhorn Mountains.
