The Adnyamathanha (Pronounced: /ˈɑːdnjəmʌdənə/) are a contemporarily formed grouping of several distinct Aboriginal Australian peoples of the northern Flinders Ranges, South Australia. The ethnonym Adnyamathanha was an alternative name for the Wailpi but the contemporary grouping also includes the Guyani, Jadliaura, Pilatapa, and sometimes the Barngarla peoples. The origin of the name is in the words "adnya" ("rock") and "matha" ("group" or "group of people"). Adnyamathanha is also used to refer to their traditional language, although Adnyamathanha people themselves call their language "yura ngarwala" (roughly translated as "our speech") and refer to themselves as "yura".
There is a community of Adnyamathanha people at Nepabunna, just west of the Gammon Ranges, which was established as a mission station in 1931. The Adnyamathanha people have run Nantawarrina IPA, the first Indigenous Protected Area in Australia, since 1998. In 2009, the Adnyamathanha people were recognised by the Federal Court of Australia as having native title rights over about 41,000 square kilometres (16,000 sq mi) running east from the edge of Lake Torrens, through the northern Flinders Ranges, approaching the South Australian border with New South Wales. It includes the Ikara–Flinders Ranges National Park. The Adnyamathanha Traditional Lands Association (ATLA) was formed to represent the interests of the Adnyamathanha people.
