Mengu-Timur (/ˈmɛŋɡuː ˈtɪmər/ MEN-goo TIM-ər) or Möngke Temür (Mongolian: ᠮᠥᠩᠬᠡᠲᠡᠮᠦᠷ, Мөнхтөмөр; died 1280) was a son of Toqoqan Khan[1] (himself the son of Batu) and Köchu Khatun of Oirat,[2] the daughter of Toralchi Küregen and granddaughter of Qutuqa Beki.

During his reign, the Mongols together with their subjects, several Turkic tribes and the Russian princes, undertook military campaigns against Byzantium (c. 1269–1271), Lithuania (1275), and the Alans in the Caucasus (1277).

The very first yarlyk (a license or written commandant of Mongol and Chinggisid rulers) found by historians was written on behalf of Mengu-Timur and contained information on the release of the Russian Orthodox Church from paying tribute to the Golden Horde, even though he was a shamanist.

The Khan also dispatched his army along with several Russian princes to Lithuania by the request of the Duke Lev of Galicia-Volhynia in 1275.

In 1277, he ended the long siege of the Alani city Dyadkov with the assistance of his Russian vassals and crushed the rebellion of the Volga Bulgars in Kazan.

That is why, the Khan of the Jochid Ulus sent 30,000 armed-men headed by his uncle Berkecher to support Kaidu's force.

In addition to the peace treaty, Abagha allowed Mongke Temur to collect tax income from some of the workshops in his khanate.

In 1276, Chingisid princes Shiregi and Tokhtemur defected to Kaidu's side and arrested Kublai's son.
