The Adnyamathanha language (pronounced /ˈɑːdnjəmʌdənə/), also known as yura ngarwala natively and Kuyani, also known as Guyani and other variants, are two closely related Australian Aboriginal languages. They are traditional languages of the Adnyamathanha of and the Kuyani peoples, of the Flinders Ranges and to the west of the Flinders respectively, in South Australia.
As of the 2016 Australian census, there were around 140 speakers of Adnyamathanha, making it an endangered language; there have been no speakers of Kuyani recorded since 1975. The first bilingual dictionary of the language was published in November 2020.
