Type 3 Medium Tank Chi-Nu (三式中戦車 チヌ, San-shiki chū-sensha Chi-nu, "Imperial Year 2603 Medium tank Model 10") was a medium tank of the Imperial Japanese Army in World War II. Like the Type 1 Chi-He, this tank was an improved version of the Type 97 Chi-Ha. It incorporated a Type 3 75 mm tank gun, one of the largest Japanese tank guns during the war.

The Chi-Nu did not see combat during the war. All produced units were retained for the defense of the Japanese Homeland in anticipation of an Allied invasion.
