The Nyonga forest tree frog (Leptopelis lebeaui) is a species of frog in the family Arthroleptidae endemic to the Democratic Republic of the Congo.Its natural habitats are rivers, freshwater marshes, and intermittent freshwater marshes. As of 2004, the Upemba National Park was the only place in which they were being protected.
The conservation status of the Nyonga forest tree frog is currently data deficient, meaning not enough information is available for a proper assessment of its conservation status.
