Choerophryne variegata is a species of frog in the family Microhylidae. It is endemic to West Papua, Indonesia, and is only known with certainty from its type locality, Digul River. It is assumed that most records from elsewhere refer to other, possibly undescribed species. As the species is only known from one specimen from its vaguely stated type locality, its ecology is essentially unknown, although it is presumed to be a rainforest inhabitant. No other specimen has been collected anywhere near the type locality. Despite all this, vernacular name common rainforest frog has been coined for it.
