Austrochaperina novaebritanniae is a species of frog in the family Microhylidae. It is endemic to the island of New Britain, Papua New Guinea. It is restricted to the northeastern part of the island where it occurs in lowland rainforests at elevations of 350m–1000mm (1,150feet–3,000feetm) above sea level. It has also been found in a recently cleared rainforest. It is threatened by the logging of lowland forest but can be locally abundant.
