Buff Island is an Antarctic island which lies 3 nautical miles (6 km) southwest of the Joubin Islands and 10.5 nautical miles (19 km) southwest of Cape Monaco, Anvers Island, at the southwest end of the Palmer Archipelago.

The island appears to be first shown and named on a 1936 chart by the British Graham Land Expedition under John Rymill.
