Paeonidae or Paionidai (Ancient Greek: Παιονίδαι),^[1] was a deme of ancient Attica, associated with the tribe (phyle) Leontis.^[2] It was apparently the same as the Paeonia or Paionia (Παιονίη), which Herodotus located as being below the Attic fortress of Leipsydrium.^[3] The site of Paeonidae is located north of modern Acharnes (formerly Menidi) at the foot of Mount Parnes.^[4]

According to the second-century geographer Pausanias, the Paeonidae were supposed to have been named after Paeon, the son of Antilochus, who was the son of Nestor, and one of the suitors of Helen, who fought in the Trojan War.^[5]
