Ngaatjatjarra (also Ngaatjatjara, Ngaadadjarra) is an Australian Aboriginal dialect of the Western Desert language. It is spoken in the Western Desert cultural bloc which covers about 600 000 square kilometres of the arid central and central-western desert. It is very similar to its close neighbours Ngaanyatjarra, Pitjantjatjara and Pintupi, with which it is highly mutually intelligible.Most Ngaatjatjarra people live in one of the communities of Warburton, Warakurna, Tjukurla or Docker River.
