Sarnoff Mountains (77°10′S 145°0′W / 77.167°S 145.000°W / -77.167; -145.000 (Sarnoff Mountains)) is a range of mountains, 251 nautical miles (465 km; 289 mi) long and 4 to 8 nautical miles (7.4 to 14.8 km; 4.6 to 9.2 mi) wide separating the west-flowing Boyd Glacier and Arthur Glacier in the Ford Ranges of Marie Byrd Land, Antarctica.

The Sarnoff Mountains are in the Ford Ranges. They run in a northwest direction between Boyd Glacier to the southwest and Arthur Glacier to the north. Features include, from northwest to southeast, Walgreen Peak, The Billboard, Mount Rea, Mount Dolber, Mount Cooper, Mount Blades, Bailey Ridge, Asman Ridge, Mount Byrd, Mount Gonzáles, Mount McClung, Fleming Peaks and Mount Crow. Nearby features on the west side of Boyd Glacier include Mount Woodward, Mount Kohler and Mount Douglass. Nearby features to the north include Rea Rocks, Mount Warner and Andrews Peaks.

The west end of the range was discovered and roughly plotted from photographs taken by the Byrd Antarctic Expedition (ByrdAE; 1928–30) on the flight of December 5, 1929. The range was mapped in greater detail by the Byrd Antarctic Expedition (1933–35) and United States Antarctic Service (USAS) (1939–41), all expeditions led by R. Admiral Richard E. Byrd. It was named for David Sarnoff, president of RCA (Radio Corporation of America), who provided radio equipment for receiving and transmitting that was used in the field and at Little America by the Byrd Antarctic Expedition (1933–35).
