Soranus of Ephesus (Ancient Greek: Σωρανός ὁ Ἑφέσιος; fl. 1st/2nd century AD) was a Greek physician. He was born in Ephesus but practiced in Alexandria and subsequently in Rome, and was one of the chief representatives of the Methodic school of medicine. Several of his writings still survive, most notably his four-volume treatise on gynecology, and a Latin translation of his On Acute and Chronic Diseases.
