Northeast Glacier is a steep, heavily crevassed glacier, 21 km (13 mi) long and 8 km (5 mi) wide at its mouth, which flows from McLeod Hill westward and then south-westwards into Marguerite Bay between the Debenham Islands and Roman Four Promontory, on the west coast of Graham Land, Antarctica. Northeast Glacier was first surveyed in 1936 by the British Graham Land Expedition (BGLE) under John Riddoch Rymill.
