Yesun Temur (Есөнтөмөр;) was a Tengric khan (r. 1337–1339)[1] of Chagatai Khanate. He was the younger brother of Changshi Khan. Their father was prince Ebugen who was the son of Duwa, the Chagatai Khan. Yesun Temur's name literally means "Nine Iron" in the Mongolian language.
In order to take power, Yesun Temur is said to have poisoned (murdered) his brother in 1337. He regretted his action and blamed his mother for Changshi's death. His guilt caused him to become very stressed, which led to excessive drinking. He was overthrown by 'Ali-Sultan of the House of Ogedei in 1339.[2]
