The Quartermain Mountains ( 77°51′S 160°45′E / 77.850°S 160.750°E / -77.850; 160.750) are a group of exposed mountains in Antarctica, about 20 nautical miles (37 km; 23 mi) long, typical of ice-free features of the McMurdo Dry Valleys, Victoria Land. They are east of the Lashly Mountains, south of the Asgard Range, west of the Kukri Hills and Royal Society Range, and some distance north of the Worcester Range.

The Quartermain Mountains were visited by British expeditions led by Robert Falcon Scott (1901–04 and 1910–13) and Ernest Shackleton (1907–09), who applied several names. Names were added in the years subsequent to the International Geophysical Year, 1957–58, concurrent with research carried out by New Zealand Antarctic Research Programme (NZARP) and United States Antarctic Research Program (USARP) field parties, and to fulfill the requirement for maps compiled from United States Navy aerial photographs, 1947–83. In 1977, the New Zealand Antarctic Place-Names Committee named the mountains after New Zealand Antarctic historian Lester Bowden Quartermain (1895–1973).

The Quatermain Mountains are east of the Lashly Mountains, from which they are separated by the Lashly Glacier. The Portal and Pivot Peak are to the southwest. The Ferrar Glacier runs along the southeast boundary, and the Taylor Glacier runs along the north and northeast boundary. The Quartermain Mountains are bounded by Finger Mountain, Mount Handsley, Mount Feather and Tabular Mountain; also including Knobhead, Terra Cotta Mountain, New Mountain, Beacon Heights, Pyramid Mountain, Arena Valley, Kennar Valley, Turnabout Valley and the several valleys and ridges within Beacon Valley.

The name is one of a group in the area associated with surveying applied in 1993 by the New Zealand Geographic Board (NZGB).

Presumably named after Thomas Kennar, Royal Navy, Petty Officer on the Discovery during the British National Antarctic Expedition (BrNAE), 1901-04, led by R.F. Scott. In November 1903, Kennar and William J. Weller (see Mount Weller) accompanied Hartley T. Ferrar in the first geological reconnaissance of the Quartermain Mountains.
