De Gerlache named this island for Madame de Rongé, a wealthy contributor to his expedition. It is home to several large colonies of gentoos and chinstraps. The cave on the hillside may have sheltered early sealers. The small archipelago called Orne Islands, just north of Rongé Island, was probably named by early 20th-century whalers working in the area. It is home to a colony of chinstraps.
