Tyberissus or Tyberissos, also Tyberisus or Tyberisos, was an inland town of ancient Lycia, near the ancient settlement of Teimiussa that functioned as its port. The name is not attested in history, but is derived from epigraphic and other evidence. This combination of harbor and inland location is the focus of archaeological exploration. Among the finds are tombs with Lycian inscriptions. Coins inscribed "ΤΥ" of typical Lycian type were probably minted here.
