Arghun Khan a.k.a. Argon (Mongolian Cyrillic: Аргун хан; c. 1258 – 7 March 1291) was the fourth ruler of the Mongol empire's Ilkhanate, from 1284 to 1291. He was the son of Abaqa Khan, and like his father, was a devout Buddhist (although pro-Christian). He was known for sending several embassies to Europe in an unsuccessful attempt to form a Franco-Mongol alliance against the Muslims in the Holy Land. It was also Arghun who requested a new bride from his great-uncle Kublai Khan. The mission to escort the young Kökötchin across Asia to Arghun was reportedly taken by Marco Polo. Arghun died before Kökötchin arrived, so she instead married Arghun's son, Ghazan.

Arghun was born to Abaqa Khan and his Christian princess wife, Haimash Khatun. Arghun himself had multiple wives, and his mother-in-law Bulughan Khatun raised Arghun's two sons Ghazan (whose birth mother was Qutlugh) and Öljeitü (whose birth mother was Uruk Khatun), both of whom later succeeded him and eventually converted to Islam. Arghun had Öljeitü baptized as a Christian at birth, and gave him the name Nikolya "Nicholas" after Pope Nicholas IV. According to the Dominican missionary Ricoldo of Montecroce, he was "a man given to the worst of villainy, but for all that a friend of the Christians".

One of the sisters of Arghun, Oljath, was married to the Georgian King Vakhtang II.
