The Adare Peninsula, sometimes called the Cape Adare Peninsula, is a high ice-covered peninsula, long, in the northeast part of Victoria Land, extending south from Cape Adare to Cape Roget. The peninsula is considered the southernmost point of the Borchgrevink Coast, named for Carsten Borchgrevink (1864-1934). The peninsula was named by the New Zealand Antarctic Place-Names Committee (NZ-APC) for Cape Adare.
