Hamaxitus was a 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 (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 Besiktepe near the village of Gülpinar (previously Külâhli) in the Ayvacik district of Çanakkale Province, Turkey.
