Secoya (also Sieko Coca, Paicoca, Airo Pãi) is a Western Tucanoan language spoken by the Secoya people of Ecuador and Peru. Included among the Secoya are a number of people called Angoteros. Although their language comprises only some dialectal differences of Secoya, there are no other communicative obstacles present. The Siona of the Eno River, linguistically different from the Siona of the Putumayo, say there are significant dialectal differences between their language and Secoya, but are still considered a part of them. In ethnographic publications, the Secoya go by other alternate names as well: Encabellado, Pioje (meaning "no" in Secoya), Santa Maria, and Angutera.
