Hermit Island is an island nearly 2 kilometres (1 nmi) long, lying 3 kilometres (1.5 nmi) southeast of Bonaparte Point, off the southwest coast of Anvers Island in the Palmer Archipelago. So named by the United Kingdom Antarctic Place-names Committee (UK-APC) in 1958 because a member of the Falkland Islands Dependencies Survey (FIDS) at the Arthur Harbor station spent some time on this island alone in January 1957, making survey observations.
