The Kartu languages are a group of Indigenous Australian languages spoken in the Murchison and Gascoyne regions of Western Australia. They are thought to be closely related and to form a low-level genealogical group. The languages usually considered to be members of the Kartu group are, from north to south: The inclusion of Nhanda is dubious. It was excluded in Bowern & Koch (2004), but retained in Bowern (2011). Thaagurda was apparently also a Kartu language. The name kartu comes from the word for 'man' in one of the languages. In some earlier work the word 'kardu' was spelled. The Kartu languages form a branch of the Pama–Nyungan family.
