Austrochaperina aquilonia is a species of frogs in the family Microhylidae. It is endemic to the Sandaun Province, north-western Papua New Guinea. It is only known from two nearby locations in the Torricelli Mountains: Mount Somoro (type locality) and from the village of Wilbeite. The specific name aquilonia is a Latin adjective meaning "northern" and refers to the range of this species in the north coast mountains of New Guinea.
