Arghūn Khān (d. 690/1291), was the son of Abāqā Khān (q.v.), grandson of Hūlāgū (Hülegü) Khān, and the fourth Īlkhānid Mongol ruler of Persia. He was Abāqā’s eldest son by Qaymish Īqāchī (Qaitmish Igechi). Of the sources written close to his time, only Rashīd al-Dīn’s Jāmiʿ al-tawārīkh gives a date as well as a place of birth for him: 660/1262 near Baylaqān (vol. 2, pp. 1150–1152).
