Markham Island (74°36′S 164°55′E) is a small but conspicuous island lying just off Oscar Point in the northern part of Terra Nova Bay, Victoria Land, Antarctica. It was discovered in February 1900 by the British Antarctic Expedition (1898–1900) under C.E. Borchgrevink, who named it for Sir Clements Markham.
