Antiphellus or Antiphellos (Ancient Greek: Ἀντίφελλος) was city that acted as the port of Phellus (Phellos) in Lycia. It was at the head of a bay on the south coast. Sir Francis Beaufort, the discoverer of this ancient site, gave the contemporary name of Vathy to the bay at the head of which Antiphellus stands. Pliny says that its ancient (i.e. pre-Hellenic) name was Habessus; he also remarks on the quality of its sponges. Strabo (14:666) incorrectly places Antiphellus among the inland towns.
