Danco Island or Isla Dedo is an island off Antarctica, 2 kilometres (1 nmi) long lying in the southern part of Errera Channel, off the west coast of Graham Land. It was charted by the Belgian Antarctic Expedition under Adrien de Gerlache, 1897–1899. Danco Island was surveyed by the Falkland Islands Dependencies Survey from Norsel in 1955, and named by the UK Antarctic Place-names Committee for Emile Danco (1869–1898), a Belgian geophysicist and member of the Belgian Antarctic Expedition, who died on board Belgica in the Antarctic.
