The Arrernte people, sometimes referred to as the Aranda, Arunta or Arrarnta, are a group of Aboriginal Australian peoples who live in the Arrernte lands, at Mparntwe and surrounding areas of the Central Australia region of the Northern Territory. Many still speak one of the various Arrernte dialects. Some Arrernte live in other areas far from their homeland, including the major Australian cities and overseas.

Arrernte or Aranda, or sometimes referred to as Upper Arrernte, is a dialect cluster in the Arandic language group spoken in parts of the Northern Territory, Australia, by the Arrernte people. Other spelling variations are Arunta or Arrarnta, and all of the dialects have multiple other names.
