Phellos (Ancient Greek: Phellus: "stony ground") was an ancient Lycian city, that first appeared in the records when it was mentioned by the Greek historian and geographer Hecataeus in c. 500 BC, who incorrectly located it in Pamphylia.
The city was a member of the Lycian League, during a period when it controlled lands in the region, and the castles at Bayındır and Limanı. Phellus was inland, and Antiphellus, a coastal settlement to the south, served as its port. During the 5th century, members of the Xanthian royal family resided there, and so the city at one time played a central political role. The city's role as a dynastic centre ended with its conquest by Perikle of Limyra in the 390s. During the Hellenistic period, Antiphellos superseded Phellus, and expanded into a thriving commercial centre, whilst Phellus diminished in importance.
