The Diaoyu Fortress or Diaoyucheng (simplified Chinese: 钓鱼城; traditional Chinese: 釣魚城; pinyin: Diàoyúchéng) is one of the great ancient battlefields of China, located on the Diaoyu Mountain in Heyang Town, Hechuan District, Chongqing. It is famous for its resistance to the Mongol armies in the latter half of the Song Dynasty. One of the most notable events was the death of Mongol leader Möngke Khan near the city, which forced the immediate withdrawal of Mongol troops from Syria and East Asia and prevented the Mongolian Empire from expanding towards Africa.

Although the Mongols and the Southern Song were united in their fight to bring down the Jurchen Jin dynasty, their pact broke immediately afterwards, and the Mongols launched an aggressive war against the tenacious Southern Song that lasted for more than a third of the 13th century. In the period from 1243 to 1279, Diaoyu experienced more than two hundred military confrontations in a miracle of "persistent resistance" that endured for thirty-six years.

The ancient Diaoyu covers an area of 2.94 square kilometres. Situated on a hill surrounded by water on three sides, it is located about five kilometers east of Hechuan, Chongqing, near the confluence of the Qu, Fu and Jialing rivers. The terrain is precipitous yet beautiful. About 700 years ago, Yu Jian built a fortress here to resist the Mongols during the Southern Song Dynasty (1127–1279).
