Stephanus of Athens (lived c. 540–680), also called Stephanus the Philosopher, was a Byzantine Greek physician and writer. A Christian native of Athens, he studied at Alexandria under a certain Asclepius, possibly Asclepius of Tralles. He later practised and taught medicine there. Stephanus' commentaries are structured as a series of lectures (praxeis) and discussions (theoriai) in the fashion of the school of Ammonius of Alexandria, the teacher of Asclepius of Tralles. He demonstrates familiarity with Greek philosophy and had probably studied it alongside medicine.
