The Huni Kuin (also known as: Kaxinawá, Cashinahua, Kaschinawa, Kashinawa, Caxinauás) are an indigenous people of Brazil and Peru. Their villages are located along the Purus and Curanja Rivers in Peru and the Tarauacá, Jordão, Breu, Muru, Envira, Humaitã, and Purus Rivers in Brazil.
In the Peruvian Amazon rainforest, some Huni Kuin live on the Alto Purús Indigenous Territory with the Kulina people.
Name
The name Huni Kuin means "true people" or "people with traditions". The alternative name Kaxinawá means "cannibals", "bat people" and "people who walk about at night". It is still widespread in literature, yet the Huni Kuin reject the name as an insult.
Language
The Huni Kuin speak the Kaxinawá language, a Panoan language. They call their language Hancha Kuin, meaning "real words." Only 5% to 10% of the Huni Kuin in Peru speak Spanish and literacy rates are low.
