休斯半岛是南极洲的半岛，位于瑟斯顿岛北部，长33公里，该半岛根据美国海军在1946年12月拍摄的空中照片绘入地图，现时由南极条约体系管理。

Hughes Peninsula (71°54′S 100°17′W / 71.900°S 100.283°W / -71.900; -100.283) is an ice-covered peninsula about 18 nautical miles (33 km) long, lying west of Henry Inlet on the north side of Thurston Island, Antarctica. It was plotted from air photos taken by U.S. Navy Operation Highjump in December 1946, and was named by the Advisory Committee on Antarctic Names for Jerry Hughes, a photographer's mate with the U.S. Navy Bellingshausen Sea Expedition in February 1960, who took aerial photographs of Thurston Island from helicopters.
