A Chinese treasure ship (simplified Chinese: 宝船; traditional Chinese: 寶船; pinyin: bǎochuán, literally "gem ship") is a type of large wooden ship in the fleet of admiral Zheng He, who led seven voyages during the early 15th-century Ming dynasty. The size of Chinese treasure ship has been a subject of debate with the History of Ming recording the size of 44 zhang or 44.4 zhang, which has been interpreted by some as over 100 m (330 ft) in length, while others have stated that Zheng He's largest ship was about 70 m (230 ft) or less in length.
