Hoste Island (Spanish: Isla Hoste) is one of the southernmost islands in Chile, lying south, across the Beagle Channel, from Isla Grande de Tierra del Fuego and west of Navarino Island, from which it is separated by the Murray Channel. Hoste Island has the southernmost trees on earth, Nothofagus antarctica. In Magellania, Jules Verne described an imaginary republic on the island.
