Adrastus of Aphrodisias (Greek: Ἄδραστος ὁ Ἀφροδισιεύς; fl. 2nd century) was a Peripatetic philosopher who lived in the first half of the 2nd century AD.[1]

He was the author of a treatise on the arrangement of Aristotle's writings and his system of philosophy which was quoted by Simplicius,[2] and by Achilles Tatius.[page needed] Some commentaries of his on the Timaeus of Plato are also quoted by Porphyry,[3] which was also used by Theon of Smyrna in the surviving sections of his On Mathematics Useful for the Understanding of Plato.[1][4] and a treatise on the Categories of Aristotle by Galen.[page needed][5]

None of these works have survived.[5] In some medieval manuscripts, a work with the title Harmonica was attributed to Adrastus, however, this was a misattribution of a work by Manuel Bryennios.[6][7] [8][9]
