Gold Hill (formerly, Orr City)[2] is an unincorporated community in Placer County, California.

[1] Gold Hill is located 6 miles (9.7 km) west of Auburn.

This West Belt contained scattered deposits of gold in quartz veins within the granitic bedrock.

In addition to the gravel deposits, the hill itself was developed by two companies, known as the Georgia and the Ohio, using ground sluicing from water in the ravine.

The town's civil government was organized in the spring of 1852, with the election of a Justice of the Peace, and a Constable.
