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[1][2] where it occurs in lowland rainforests at elevations of 350–1,000 m (1,150–3,280 ft) 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.
