Oreophryne furu is a species of microhylid frogs endemic to the Mamberamo River basin in Papua, Western New Guinea.

[1][3] It is distinguished from other related species by its small size, unique call and egg-guarding behaviour.

[2] O. furu was first collected in 2000 during a Conservation International biodiversity survey, and formally described in 2009 by Rainer Günther, Stephen Richards, Burhan Tjaturadi and Djoko Iskandar.

It was found in the lowland rainforest (90 m (300 ft) above sea level) near the Mamberamo River of Western New Guinea.

The dorsal and lateral sides are pale grey with variously scattered dark brown pigmentation, and a whitish mask on the snout.
