Heraclea at Latmus (Ancient Greek: Ἡράκλεια πρὸς Λάτμῳ, romanized: Herakleia pros Latmo; Latin: Heraclea ad Latmum), or simply Heraclea or Herakleia (Ἡράκλεια), also transliterated as Heracleia, was a town on the confines between ancient Caria and Ionia, situated at the western foot of Mount Latmus on the Gulf of Latmus, which has since silted up. During the Hellenistic period it bore the name Pleistarcheia, probably after Pleistarchus. It was a small place in the south-east of Miletus, and south-west of Amyzon. In its neighbourhood a cave was shown with the tomb of Endymion. Ruins of this town still exist at the foot of mount Latmus on the borders of Lake Bafa, which is probably a portion of the ancient Sinus Latmicus, formed by the deposits of the river Maeander.
