Hestiaea or Hestiaia (Ancient Greek: Ἑστιαία), also known as Histiaea or Histiaia (Ἱστίαια), was a deme of ancient Attica located northeast of Athens, near the modern Tsako, near Cholargos.^[1]

Very little is known of Hestiaea. According to Strabo its citizens originally founded the homonymous city in the north of the island Euboea;^[2] this theory, however, could have arisen in the late period and therefore would be unfounded.
