Kököchin, also Kökejin, Kūkājīn, Cocacin or Cozotine (Mongolian: ᠬᠥᠬᠴᠢᠨ Хөхчин; Chinese: 闊闊真; pinyin: kuò kuò zhēn), was a 13th-century princess of the Mongol-led Chinese Yuan dynasty, belonging to the Mongol Bayaut tribe. In 1291, she was betrothed to the Ilkhanate khan Arghun by the Yuan founding emperor Kublai, but eventually was married to his son Ghazan when Arghun died by the time she arrived in Persia in 1293. The account of Kököchin's journey to Persia was given by Marco Polo, who was part of her entourage.
