The Willis Islands are a small archipelago to the west of South Georgia Island in the South Georgia Islands. They are 2 miles (3.2 km) west of Bird Island, separated by the Stewart Strait. They were discovered on 14 January 1775 by Captain James Cook and named for Cook's midshipman Thomas Willis, the crew member who first sighted them. The Willis Islands were charted in greater detail and individually named by Discovery Investigations (DI) personnel between 1926 and 1930.
