Leonie Islands () is a group of small islands lying in the entrance to Ryder Bay along the southeast side of Adelaide Island. The French Antarctic Expedition under Charcot, 1908–10, discovered these islands and gave the name Leonie to the largest island. The British Graham Land Expedition (BGLE) under Rymill, 1934–37, extended the coverage of the name to the entire group.
