The Quanzhou Ship (泉州湾古船), or Quanzhou wreck, was a 13th-century Chinese seagoing sailing junk that sank near the city of Quanzhou in Fujian Province, and was discovered in 1973. It remains one of the most important marine archaeology finds in China, and is an important piece of physical evidence about the shipbuilding techniques of the Song China and the international maritime trade of the period.
