Powningville is a former settlement in El Dorado County, California, United States. It was located to east-northeast of Pilot Hill. Amos Bowman's map of the Georgetown Divide in El Dorado County shows a single tunnel owned by the Fairmount Copper Mining Company in the hill north of the town. Sometime before 1883, Powningville was involved in a dispute with the Nevada state government regarding a state prison.
