Philo of Larissa (Greek: Φίλων ὁ Λαρισσαῖος Philon ho Larissaios; 159/8–84/3 BC) was a Greek philosopher. He was a pupil of Clitomachus, whom he succeeded as head of the Academy. During the Mithridatic wars which would see the destruction of the Academy, he travelled to Rome where Cicero heard him lecture. None of his writings survive. He was an Academic sceptic, like Clitomachus and Carneades before him, but he offered a more moderate view of scepticism than that of his teachers, permitting provisional beliefs without certainty.
