The Churchill Mountains is a major range of mountains and associated elevations bordering the western side of the Ross Ice Shelf, between Byrd Glacier and Nimrod Glacier. They are south of the Britannia Range and north of the Geologists Range, Miller Range and Queen Elizabeth Range.

Exploration and naming

Several of the range's highest summits, including Mount Egerton, Mount Field, Mount Nares, Mount Wharton, and Mount Albert Markham were first seen and named by the British National Antarctic Expedition of 1901–1904 under Robert Falcon Scott. The mountains were mapped in detail by the USGS from tellurometer surveys during 1960–61, and by United States Navy air photos in 1960. They were named by the United States US-ACAN for Sir Winston Churchill.
