Antiochus of Ascalon (; ; c. 125 – c. 68 BC) was an Academic philosopher. He was a pupil of Philo of Larissa at the Academy, but he diverged from the Academic skepticism of Philo and his predecessors. He was a teacher of Cicero, and the first of a new breed of eclectics among the Platonists; he endeavoured to bring the doctrines of the Stoics and the Peripatetics into Platonism, and stated, in opposition to Philo, that the mind could distinguish true from false. In doing so, he claimed to be reviving the doctrines of the Old Academy. With him began the phase of philosophy known as Middle Platonism.
