King Peninsula (72°12′S 100°15′W / 72.200°S 100.250°W) is an ice-covered peninsula, 100 miles long and 20 miles wide, lying south of Thurston Island and forming the south side of Peacock Sound. It projects from the continental ice sheet and trends west between the Abbot Ice Shelf and Cosgrove Ice Shelf to terminate at Amundsen Sea. The feature was photographed from the air by USN Operation Highjump, 1946–47, and was plotted from these photos as a long island, or possible peninsula. Photos taken by USN in 1966 show it is a peninsula.
King Peninsula was named by the Advisory Committee on Antarctic Names (US-ACAN) for Fleet Admiral Ernest J. King, USN, Chief of Naval Operations from 1942–45, who approved the preliminary work for Operation Highjump.
