The Warlpiri, sometimes referred to as Yapa, are a group of Aboriginal Australians defined by their Warlpiri language, although not all still speak it. There are 5,000–6,000 Warlpiri, living mostly in a few towns and settlements scattered through their traditional land in the Northern Territory, north and west of Alice Springs. About 3,000 still speak the Warlpiri language. The word "Warlpiri" has also been romanised as Walpiri, Walbiri, Elpira, Ilpara, and Wailbri.
