The blue finch or yellow-billed blue finch (Rhopospina caerulescens) is a species of small bird. Although it was long classified in the bunting family Emberizidae,^[1]^[2] or the cardinal family Cardinalidae,^[3] more recent molecular studies have shown it fits comfortably in the Thraupini tribe within the family Thraupidae.^[4]

It is found in Brazil and northeastern Bolivia, where its natural habitat is dry savanna. It is becoming rare due to habitat loss.^[1]
