The Bininj are an Aboriginal Australian people of Western Arnhem land in the Northern Territory. The sub-groups of Bininj are sometimes referred to by the various language dialects spoken in the region, that is, the group of dialects known as Bininj Kunwok; so the people may be named the Kunwinjku, Kuninjku, Kundjeyhmi (Gundjeihmi), Manyallaluk Mayali, Kundedjnjenghmi and Kune groups.\

Three languages are spoken among the Mirrar or Mirarr clan group, who are prominent in matters relating to looking after the traditional lands. The majority speak Kundjeyhmi, while others speak Gaagudju and others another language.
