The Kawasaki Ki-10 (九五式戦闘機, Kyūgo-shiki sentōki^?, Army Type 95 Fighter) was the last biplane fighter used by the Imperial Japanese Army, entering service in 1935. Built by Kawasaki Kōkūki Kōgyō K.K. for the Imperial Japanese Army, it saw combat service in Manchukuo and in north China during the early stages of the Second Sino-Japanese War. Its reporting name given by the Allies was "Perry".

The Ki-10 was designed by Japanese aeronautical engineer Takeo Doi, who had succeeded Richard Vogt as chief designer for Kawasaki. The design was in response to a requirement issued by the Imperial Japanese Army for a new fighter, and was the winner of a competition against Nakajima's Ki-11. Although the low-wing monoplane offered by Nakajima was more advanced, the Army preferred the more maneuverable biplane offered by Kawasaki. In order to overcome the speed disadvantage the Kawasaki team used a metal three-blade propeller in the third prototype, while flush-head rivets were used in an attempt to reduce drag.
