The Battle of Orbulaq was fought in 1643 between Jahangir Khan and Huntaiji Erdeni Batur, resulting in the defeat of Erdeni Batur's army by the Jalantush Bahadur's Kazakhs, led by Jahangir Sultan (later Jahangir Khan) with the assistance of the Uzbek Emir of Samarkand. The battle, fought during a series of Kazakh-Dzungar Wars, was one of the initial turning points in the liberation war of the Kazakhs against the Dzhungar invasion in the 17th century.
