Lichen Island is a small island lying 50NaN0 north of the Bølingen Islands and 2.50NaN0 north-west of Cleft Island in southern Prydz Bay, Antarctica. It was first visited by an Australian National Antarctic Research Expeditions party led by Phillip Law, on 5 February 1955, and named by him for the rich growth of lichens found there.
