Urarina

The Urarina are an indigenous people of the Peruvian Amazon Basin (Loreto) who inhabit the valleys of the Chambira, Urituyacu, and Corrientes Rivers. According to both archaeological and historical sources, they have resided in the Chambira Basin of contemporary northeastern Peru for centuries. The Urarina refer to themselves as Kachá (lit. "person"), while ethnologists know them by the ethnonym Urarina.

The local vernacular term for the Urarina is Shimaku, which is considered by the Urarina to be pejorative, as it is a Quechua term meaning "unreliable". The ethnonym "Urarina" may be from Quechua--uray meaning below, and rina referring to runa, or people. Urarina is rendered in Quechua as uray-runa or people from below or down stream people.
