The Azores chaffinch (Fringilla moreletti) is a small passerine bird in the finch family Fringillidae, closely related to the Eurasian chaffinch F. coelebs, and formerly treated as a subspecies of it. Genetic, morphological, and vocal differences from it have resulted in it being elevated to species level in 2021. It is endemic to the Portuguese archipelago of the Azores, part of Macaronesia in the warm temperate northern Atlantic Ocean. It is locally known as the tentilhão or sachão.
