Pentele (Greek, Ancient (to 1453);: Πεντέλη) was a deme of ancient Attica, situated at the north-eastern extremity of the Athenian plain, at the marble quarries of Mount Brilessus, which was called Mount Pentelicus from this place. The fact of Pentele being a deme rests upon the authority of Stephanus of Byzantium alone, and has not yet been confirmed by inscriptions.
The site of Pentele is tentatively located near modern Penteli.
