The Kawasaki Ki-32 (九八式軽爆撃機, Kyuhachi-shiki keibakugekiki) was a Japanese light bomber aircraft of World War II. It was a single-engine, two-seat, mid-wing, cantilever monoplane with a fixed tailwheel undercarriage. An internal bomb bay accommodated a 300 kg (660 lb) offensive load, supplemented by 150 kg (330 lb) of bombs on external racks. During the war, it was known by the Allies by the name Mary.

The Ki-32 saw extensive war service in the Second Sino-Japanese War, equipping the 3rd, 6th, 10th, 35th, 45th, 65th and 75th Sentai. It also saw combat during the Battle of Nomonhan against the Soviet Union in 1938–1939. Its last combat action was bombing Commonwealth forces during the Japanese invasion of Hong Kong in December 1941.[3] After their withdrawal from front-line service in 1942, the Ki-32s were used in a training role.

During World War II, the Japanese also supplied Ki-32s to the Manchukuo Air Force to replace Manchukuo′s obsolescent Kawasaki Type 88/KDA-2 light bombers. Ki-32s were the main bomber of the Manchukuo Air Force throughout World War II.
