Rashīd al-Dīn Ṭabīb (Persian: رشیدالدین طبیب; 1247–1318; also known as Rashīd al-Dīn Faḍlullāh Hamadānī, Persian: رشیدالدین فضلالله همدانی) was a statesman, historian, and physician in Ilkhanate Iran.
Having converted to Islam from Judaism by the age of 30 in 1277, Rashid al-Din became the powerful vizier of Ilkhan Ghazan. He was commissioned by Ghazan to write the Jāmiʿ al-Tawārīkh, now considered the most important single source for the history of the Ilkhanate period and the Mongol Empire. He retained his position as a vizier until 1316.
