Lama Dorji, or Lama Darja (Mongolian: Лхамдаржаа; Chinese: 喇嘛達爾札; 1726 or 1728–1753) was a mid-eighteenth century khan or ruler of the Dzungar Khanate, a confederation of Mongol tribes that ruled over most of present-day Xinjiang and part of eastern Kazakhstan, Kyrgyzstan and southern Siberia.
Before his death, Galdan Tseren had designated his second son Tsewang Dorji Namjal to succeed him.
[2] Despite his low birth as a Khoit, Lama Dorji's encountered little opposition except from the Dzungar Khan, Dawachi, grandson of Khong Tayiji and Tsewang Rabtan's cousin Tsering Dhondup (大策凌敦多布).
[3] In 1751, Lama Dorji defeated Dawachi, who was forced to flee across the border into Kazakh Khanate territory with about a dozen men.
With a thousand men, he then marched to Ili where they surprised Lama Dorji and killed him on 13 January 1753.
