Philotas of Amphissa (Greek: Φιλώτας) was a physician of the 1st century BC.
He studied at Alexandria, and was in that city at the same time with the triumvir Mark Antony, of whose profusion and extravagance he was an eye-witness.
He became acquainted with the triumvir's son Antyllus, with whom he sometimes supped, about 30 BC.
As Antyllus was quite a lad at that time, Philotas scrupled to accept such a gift, but was encouraged to do so by one of the attendants, who asked him if he did not know that the giver was a son of the triumvir Antonius, and that he had full power to make such presents.
He may perhaps be the same physician, of whose medical formulae one is quoted by Aulus Cornelius Celsus and Asclepiades Pharmacion, and who must have lived in or before the 1st century BC.
