Elephant Spit is a 9 km long sand spit at the eastern end of subantarctic Heard Island, in the Australian territory of Heard Island and McDonald Islands, lying in the Southern Ocean on the Kerguelen Plateau about 450 km south-east of the Kerguelen Islands. The name refers to southern elephant seals, also known as sea elephants, which breed in large numbers on Heard Island and formed the basis for commercial sealing for oil there during the 19th century.
