Lion Island, Palmer Archipelago

Lion Island is an island 1.5 nautical miles (2.8 km) long and 1 nautical mile (1.9 km) wide, lying off the east side of Anvers Island and 1 nautical mile (1.9 km) northeast of Cape Astrup, Wiencke Island, in the Palmer Archipelago off the Antarctic Peninsula.

It was discovered by the Belgian Antarctic Expedition, 1897–1899, under Adrien de Gerlache. The name appears on a map based on a 1927 survey by Discovery Investigations personnel on the RRS Discovery. The profile of the island suggests a reclining lion when viewed from the southwest.
