Psychrophrynella usurpator is a species of frogs in the family Craugastoridae. It is endemic to Peru and known from near Abra Acjanacu (its type locality), a mountain pass in the Cordillera de Paucartambo, the easternmost Andean range towards the Amazonian lowlands, and from the high elevation grasslands of the Manu National Park. It is named usurpator because these frogs were previously misidentified as Noblella peruviana —in a sense, they had "usurped" the name of another frog species.
