Каяпо

Also known as Caiapos

The Kayapo (Portuguese: Caiapó ) people are an indigenous people in Brazil, living over a vast area across the states of Pará and Mato Grosso, south of the Amazon River and along the Xingu River and its tributaries. This location has given rise to the tribe's nickname of "the Xingu". They are one of the various subgroups of the great Mebêngôkre nation (meaning "people from the water's source"). The name Kayapo is used by neighboring groups rather than referring by the Kayapo to themselves; they refer to outsiders as Poanjos.
