Aṉangu Pitjantjatjara Yankunytjatjara, also known as APY, APY Lands or the Lands, is a large, sparsely-populated local government area (LGA) for Aboriginal people, located in the remote north west of South Australia. Some of the Aṉangu (people) of the Western Desert cultural bloc, in particular Pitjantjatjara, Yankunytjatjara and Ngaanyatjarra peoples, inhabit the Lands.

The Pitjantjatjara are an Aboriginal people of the Central Australian desert near Uluru. They are closely related to the Yankunytjatjara and Ngaanyatjarra and their languages are, to a large extent, mutually intelligible.
