Bear Island or Isla Teniente González is a rocky island lying 1.6 kilometres (1 mi) west of Stonington Island in Marguerite Bay, off the coast of Graham Land. Bear Island was presumably known to the British Graham Land Expedition (BGLE) (1934-1937) and the United States Antarctic Service (USAS) Expedition (1939-1941), both based in the Stonington Island area.
