Olancha was established by Minnard Farley, who came to the area in 1860 and discovered silver ore in the nearby Coso Range. The name "Olancha" is believed to be derived from the nearby Yaudanche tribe. For processing the ore, he built a stamp mill just south of Olancha Creek. The remains of a stone wall from this mill still exists and has been designated as a California Historical Site (marker #796).
The first post office at Olancha opened in 1870.
