The Unggarranggu, also traditionally transcribed as Ongkarango, are an Aboriginal Australian people of the Kimberley region of Western Australia.
Along with the Yawijibaya people, they are the traditional owners of Buccaneer Archipelago, off Derby, together known as the Mayala group for native title purposes.
[2] The Unggarranggu by Norman Tindale's estimate had a domain extending over roughly 1,000 square kilometres (400 sq mi), ranging from the northeastern area of King Sound, the eastern side of Stokes Bay, and reaching north as far as Crawford Bay.
[3] The Unggarranggu were basically a coastal people dwelling on the mainland, but were on close terms with the more maritime Umiida.
Like the Umiida they plied rafts fashioned from mangrove woods, with which they would sail out to places like the island of Wilima off the mouth of Meda River, close to Warrwa territory.
