Potamo or Potamon (Greek: Ποτάμων ὁ Μυτιληναῖος; c. 75 BC – c. 15 AD) of Mytilene in Lesbos, son of Lesbonax the rhetorician, was himself a rhetorician in the time of the Roman emperor Tiberius, whose favour he enjoyed. He is mentioned by Plutarch as an authority regarding Alexander the Great. It is probably he whom Lucian states to have attained the age of ninety.
The Suda informs us that, in addition to his work On Alexander of Macedon (Περὶ Ἀλεξάνδρου τοῦ Μακεδόνος), he wrote several other works, namely:
To these should perhaps be added On the Different, quoted by Ammonius Grammaticus.
