The Amahuaca or Amhuaca are indigenous peoples of the southeastern Amazon Basin in Peru and Brazil. Isolated until the 18th century, they are currently under threat from ecological devastation, disease and violence brought by oil extractors and illegal loggers. In 1998 they numbered about 520. The largest community of the Amahuaca is in Puerto Varadero, a jungle community on the Peruvian–Brazilian border.
The Amahuaca are also known as the Amaguaco, Amawaca, Amawáka, Amawaka, Amenguaca, Ameuhaque, Ipitineri, Sayaco, Sayacu, or Yora people.
As of 2000, approximately 330 of the 500 Amahuaca spoke the Amahuaca language, a Panoan language. The language is written in the Latin script, and a grammar has been published. From 1963 to 1997, portions of the Bible were translated into Amahuaca.
