The yellow-browed toucanet (Aulacorhynchus huallagae) is a rare species of bird in the Ramphastidae family. Among the least known members of the family, it is endemic to humid forests growing on the east Andean slope in northern Peru. This species is extremely range-restricted and is known from only three small and relatively inaccessible locations in Peru: Cumpang/Utcubamba in La Libertad Region, Río Abiseo National Park, San Martín Region, and Leymebambe. It is threatened by habitat loss, and consequently considered endangered by IUCN.
