Apaturia () were ancient Greek festivals held annually by all the Ionian towns, except Ephesus and Colophon. At Athens the Apaturia took place on the 11th, 12th and 13th days of the month of Pyanepsion (mid-October to mid-November), on which occasion the various phratries, or clans, of Attica met to discuss their affairs.
