Heald Island () is an island, 3 miles (4.8 km) long and 555 m high, which projects through the ice of the Koettlitz Glacier just east of Walcott Bay, in Victoria Land. It was discovered and named by the Discovery expedition (1901–04) for Seaman William L. Heald, a member of the expedition who saved the life of Ferrar when the latter was suffering from scurvy in 1902.
