The Haines Mountains (77°34′S 146°20′W / 77.567°S 146.333°W / -77.567; -146.333 (Haines Mountains)) are a range of ice-capped mountains trending northwest–southeast for about 25 nautical miles (46 km; 29 mi) and forming the southwest wall of Hammond Glacier, in the Ford Ranges of Marie Byrd Land, Antarctica.

The Haines Mountains run southeast from Court Ridge, which extends into the Sulzberger Ice Shelf along the side of the Hammond Glacier to the head of the glacier. They are parallel to the Hershey Ridge, which lies to the west. Features, from north to south, include Alexander Peak, Buennagel Peak, Rucker Spur, Mount Ronne, Leach Nunatak, Keyser Nunatak, Reynolds Glacier, Mount Van der Veer and Kalafut Nunatak. Nearby features, on the east side of Hammond Glacier, include Mount West, Midkiff Rock and Murphy Rocks.

The Haines Mountains were discovered by the Byrd Antarctic Expedition (ByrdAE) in 1934, and named for William C. Haines, the meteorologist of the Byrd expeditions of 1928–30 and 1933–35.
