Qutuqtu (Chinese: 忽覩都, Mongolian: Хутагт) was the second son of Tolui and Lingqun Khatun (daughter of Kuchlug). He was the grandson of Genghis Khan.[1] Although he took part in Ogedei Khan's invasion of Song,[2] Qutuqtu was killed in battle against the Song general Meng Yu (孟珙).
Although Qutuqtu left no male descendants, he had a daughter, Kelmish Agha, who was instrumental in cementing the Yuan-Golden Horde alliance. Kelmish, married to Saljidai Gurkhan, gave birth to a daughter, Oljai Khatun. Oljai married Mengu-Timur (a descendant of Jochi) and gave birth to Toqta Khan of the Golden Horde.
Qutuqtu's full-sister, Ile Temür, married Pars Buqa, grandson of Quduka Beki of the Oirat tribe.[3]
