The Huolongjing (; Wade-Giles: Huo Lung Ching; rendered in English as Fire Drake Manual or Fire Dragon Manual), also known as Huoqitu (“Firearm Illustrations”), is a Chinese military treatise compiled and edited by Jiao Yu and Liu Bowen of the early Ming dynasty (1368–1683) during the 14th century. The Huolongjing is primarily based on the text known as Huolong Shenqi Tufa (Illustrations of Divine Fire Dragon Engines), which no longer exists.
