Guden Khan (Mongolian: Гүдэн Хаан; Chinese: 庫騰汗), who was born Daraisung (or Darayisung; Mongolian: Дарайсун; Chinese: 打來孫), (c. 1520–1557) was a khagan of the Northern Yuan dynasty, reigning from 1547 to 1557. He was the eldest son of Bodi Alagh Khan, whom he succeeded as khagan.
During his rule, Altan Khan, who led the Tümed Mongols at the time, became more powerful and also more disrespectful of the power of the Great Khan. Daraisung Khan was unable to achieve victory in the conflicts that arose from this. Altan Khan eventually forced Daraisung Guden Khan to flee eastward. Four years later in 1551, Daraisung made a compromise with Altan accepting Altan's leadership in exchange for giving the title "Gegeen Khan" to him. As a result, Daraisung Guden Khan was forced to relocate his imperial court to the east near Manchuria, and the power of the Great Khan began to decline. Although most Mongol nobles still recognized the Great Khan as the leader, it was in name only and two Borjin nobles declared themselves as khans of their own territories during this period.
