Potone[pronunciation?] (Greek: Πωτώνη Pōtónē or Ποτώνη Potónē; born before 427 BC) daughter of Ariston and Perictione, was Plato's older sister.[1] Her mother was Perictione and she was born in Collytus, just outside Athens. She married Eurymedon of Myrrhinus, by whom she bore Speusippus.[2]

In Roger Scruton's mock Platonic dialogue Perictione in Colophon he introduces a daughter of Potone called Perictione.
