Hump Island is an island just east of the East Arm of Horseshoe Harbour in Holme Bay, Mac. Robertson Land, Antarctica. It was mapped by Norwegian cartographers from air photos taken by the Lars Christensen Expedition, 1936–37, rephotographed by U.S. Navy Operation Highjump, 1946–47, and so named by the Australian National Antarctic Research Expeditions because of its humped appearance from ground level.
