Cothocidae or Kothokidai (Greek, Ancient (to 1453);: Κοθωκίδαι) was a deme of ancient Attica, originally of the phyle of Oeneis, but between 307/306 BCE and 201/200 BCE of the phyle of Demetrias, sending two delegates to the Athenian Boule.[1]
Its site is tentatively located near Ag. Ioannes, north of modern Aspropyrgos.
