Mount Markham (82°51′S 161°21′E / 82.850°S 161.350°E / -82.850; 161.350 (Mount Markham)) is a twin-peaked massif surmounting the north end of the Markham Plateau in the Queen Elizabeth Range of Antarctica. The peaks have elevations of 4,350 metres (14,270 ft) and 4,280 metres (14,040 ft).

Mount Markham was discovered by the British National Antarctic Expedition of 1901–1904). It is named for Sir Clements Markham, who, as President of the Royal Geographical Society, planned the expedition and chose Robert Falcon Scott as its leader.

Mount Markham is in the northern part of the Queen Elizabeth Range. It is south of Mount Cara, east of the Frigate Range and the head of the Kent Glacier, and northeast of the Markham Plateau. Nearby features include Mount Lysaght to the north, Mount Katsufrakis to the south and Haven Hill, Mount Tedrow and Mount Predoehl to the east.
