The Type 5 medium tank Chi-Ri (五式中戦車 チリ Go-shiki chusensha Chi-ri) was the penultimate medium tankdeveloped by the Imperial Japanese Army in World War II. Intended to be a heavier, more powerful version of Japan's sophisticated Type 4 Chi-To medium tank, in performance it was designed to surpass the US M4 Sherman medium tanks being fielded by the Allied forces. The single prototype was still being built when the war ended.

A single unarmed prototype of the Type 5 Chi-Ri was completed by May 1945. The project was abruptly abandoned to free up manpower and critical resources to concentrate on the development and production of the more practical Type 4 Chi-To medium tank. As with many innovative weapons projects launched by Japan in the final days of World War II, production could not advance beyond the prototype stage due to material shortages, and the loss of Japan's industrial infrastructure to the Allied bombing of
Japan.
