Nameless Glacier is a glacier that descends westward from Adare Peninsula and discharges into Protection Cove, Robertson Bay, 2 nautical miles (3.7 km) north of Newnes Glacier. It was charted and named by the Northern Party of the British Antarctic Expedition, 1910-13. This was the only one of the Robertson Bay glaciers that was left unnamed by C.E. Borchgrevink, who headed the Southern Cross Expedition, 1898-1900.
