Tetrapolis (Greek: Τετράπολις) comprised one of the twelve districts into which Attica was divided before the time of Theseus. The district was on a plain in the northeastern part of Attica and contained four cities: Marathon (Μαραθών), Probalinthus (Προβάλινθος), Tricorythus (Τρικόρυθος), and Oenoe (Οἰνόη). Stephanus of Byzantium claimed Huttēnia (Ὑττηνία) was its name among the Pelasgoi.
