The Nakajima Ki-201 Karyū (中島 キ201 火龍, "Fire Dragon") was a Japanese jet fighter/attack aircraft project designed during the final stages of World War II but which was not built.

The unrelated and much smaller Nakajima Kikka had been developed as a result of interest by the Navy in an equivalent to the German Messerschmitt Me 262, but the similarities to that aircraft were very limited.

[1] On the other hand, the design team led by Iwao Shibuya based the Karyū more closely on the German aircraft, but was over 8% larger.

The Ki-201 project was ordered by the Imperial Japanese Army in late 1944, with a performance requirement of an 800–1,000 km/h (500–620 mph) top speed, 12,000 m (39,000 ft) ceiling, and a 800–1,000 km (500–620 mi) range.

[2] Nakajima anticipated the completion of the first prototype Karyū by December, and the first 18 pre-production aircraft by March 1946.
