Daphnus or Daphnous was a city on the Euboean Sea, originally belonging to ancient Phocis, which thus extended from the Corinthian Gulf to the Euboean sea. Its narrow territory separated the Locri Epicnemidii from the Locri Opuntii; but it was afterwards assigned to the Opuntii. The town was in ruins in the time of Strabo, who fixes its site by describing it as 20 stadia distant from Cynus and 120 from Elateia, and as having a harbour. Daphnus appears in an inscription dated to 407 BCE. Daphnus lay at the head of a pass that was one of the major arteries from northern to central Greece.
