The Aparai and the Wayana are peoples of the Cariban (Karib), Central language family who inhabit the frontier region between Brazil, Surinam, and French Guiana. In Brazil they are near the East Paru River, and in the state of Pará; in Surinam they are near the Tapanahoni and Paloemeu rivers; and in French Guiana they are near the upper Maroni River and its tributaries: the Tampok and Marouini. In Brazil the Aparai and Wyana have lived together for at least a hundred years in the same villages, marrying amongst themselves. Consequently, very often one finds references to this population as a single group, although their internal differences may be claimed on the basis of distinct historical trajectories and cultural traits.

Aparai is spoken by about 564 speakers. It is also referred to by some as Apalay, Aparaí, or Arakwayu. The ISO code is apy. Literacy and grammar materials have been produced in the language.
