Aethalidae or Aithalidai (Ancient Greek: Αἰθαλίδαι) was a deme of ancient Attica, originally of the phyle of Leontis but after 307/6 BCE, of the phyle of Antigonis, sending two delegates to the Athenian Boule.[1]
It is not known for certain where it was located,[2] but it was probably close to Eupyridae, Cropia and Peleces.
