Aguano is the extinct language of the Aguano people of Peru. Loukotka (1968) identified it with Chamicuro, but Chamicuro speakers say that the Aguano people spoke Quechua . However, Steward (1946) notes that the Aguano had adopted Quechua soon after the Conquest and that their original language is unclassified. More recently, Campbell & Grondona (2012) leave Aguano unclassified due to lack of attestation. According to Glottolog, the language is Arawakan.
