Elcho Island, known to its traditional owners as Galiwin'ku (Galiwinku) is an island off the coast of Arnhem Land, in the Northern Territory of Australia. It is located at the southern end of the Wessel Islands group located in the East Arnhem Region. Galiwin'ku is also the name of the settlement where the island's largest community lives. Elcho Island formed part of the traditional lands of the Yan-nhaŋu, according to Norman Tindale. According to J. C. Jennison, the Aboriginal inhabitants were the Dhuwal, who called themselves the Kokalango Mala
