Ibn Abī Uṣaybiʿa Muʾaffaq al-Dīn Abū al-ʿAbbās Aḥmad Ibn Al-Qāsim Ibn Khalīfa al-Khazrajī (Arabic: ابن أبي أصيبعة‎; 1203–1270), commonly referred to as Ibn Abi Usaibia (also Usaibi'ah, Usaybea, Usaibi`a, Usaybiʿah, etc.), was a physician from Syria in the 13th century CE. He compiled a biographical encyclopedia of notable physicians, from the Greeks, Romans and Indians up to the year 650AH/1252AD in the Islamic era.

Ibn Abi Usaibia was born at Damascus, a member of the Arab Banu Khazraj tribe. The son of a physician, he studied medicine at Damascus and Cairo. In 1236, he was appointed physician to a new hospital in Cairo, but the following year he took up an offer by ruler of Damascus, of a post in Salkhad, near Damascus, where he lived until his death.^[1] His only surviving work is Lives of the Physicians. In that work, he mentions another of his works, but it has not survived.^[2]

The title in Arabic, Uyūn ul-Anbāʾ fī Ṭabaqāt al-Aṭibbā (Arabic: عيون الأنباء في طبقات الأطباء), is translatable loosely and expansively as "Sources of News on Classes of Physicians", commonly translated into English as History of Physicians, Lives of the Physicians, Classes of Physicians, or Biographical Encyclopedia of Physicians.^[2] The book opens with a summary of the physicians from ancient Greece, Syria, India and Rome but the main focus of the book's 700 pages is physicians of medieval Islam. A first version appeared in 1245–1246 and was dedicated to the Ayyubid physician and vizier Amīn al-Dawlah. A second and enlarged recension of the work was produced in the last years of the life of the author, and circulated in at least two different versions, as shown by the extant manuscripts.
