The Williams Hills were mapped by the United States Geological Survey (USGS) from surveys and United States Navy air photographs in 1956–1966. They were named by the United States Advisory Committee on Antarctic Names (US-ACAN) for Paul L. Williams, USGS geologist with the Neptune Range field party in 1963–64.

The Williams Hills are in the southwest of the Neptune Range on the east side of the Foundation Ice Stream. They are south of the Schmidt Hills and west of the southern end of the Washington Escarpment, from which they are separated by the Roderick Valley. Named features include, from south to north, Mount Hobbs, Pillow Knob and Teeny Rock.
