Hamaxitus (Ancient Greek: Ἁμαξιτός, romanized: Hamaxitos) was an ancient Greek city in the south-west of the Troad region of Anatolia which was considered to mark the boundary between the Troad and Aeolis. Its surrounding territory was known in Greek as Ἁμαξιτία (Hamaxitia), and included the temple of Apollo Smintheus, the salt pans at Tragasai, and the Satnioeis river (modern Tuzla Çay). It has been located on a rise called Beşiktepe near the village of Gülpınar (previously Külahlı) in the Ayvacık district of Çanakkale Province, Turkey.
