Lamplugh Island () is an ice-capped island, 10 nautical miles (18 km) long, lying 4 nautical miles (7 km) north of Whitmer Peninsula, along the coast of Victoria Land. This feature was first sighted by the Discovery expedition led by Scott, 1901–04, but it was first charted as an island by the British Antarctic Expedition under Shackleton, 1907-09. Named by Shackleton for G.W. Lamplugh, who gave assistance to the expedition.
