The Wirangu language, also written Wirrongu, Wirrung, Wirrunga, and Wirangga, and also known by other exonyms, is a moribund Australian Aboriginal language traditionally spoken by the Wirangu people, living on the west coast of South Australia across a region encompassing modern Ceduna and Streaky Bay, stretching west approximately to the head of the Great Australian Bight and east to Lake Gairdner. It is a language of the Thura-Yura group, and some older sources placed it in a subgroup called Nangga.
