The Nakajima Ki-116 was a late-World War II aircraft developed for the Imperial Japanese Army Air Force. It was essentially a Ki-84 Hayate with the Nakajima Ha-45 engine replaced with a Mitsubishi Ha-112. The design was handled by Mansyū (満州) Aircraft in Manchukuo, and thus it is often designated Mansyū Ki-116.
