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 was developed in response to a May 1936 Imperial Japanese Army specification to replace the Kawasaki Ki-3 light bomber with a completely indigenously designed and built aircraft. Mitsubishi and Kawasaki were requested to build two prototypes each by December 1936. The specification called for a top speed of 400 km/h (250 mph) at 3,000 m (9,800 ft); normal operating altitude from 2,000–4,000 m (6,600–13,100 ft), the ability to climb to 3,000 m (9,800 ft) within 8 minutes and an engine to be selected from the 825 hp (620 kW) Mitsubishi Ha-6 radial, 850 hp (630 kW) Nakajima Ha-5 radial, or 850 hp (630 kW) Kawasaki Ha-9-IIb liquid-cooled inline engines, a normal bomb load of 300 kg (661.4 lb) and a maximum of 450 kg (992.1 lb), one forward-firing machine gun and one flexible rearward-firing machine gun, the ability to perform 60-degree dives for dive bombing, and a loaded weight less than 3,300 kg (7,275.3 lb).
