Madytus or Madytos (Ancient Greek: Μάδυτος) was a Greek city and port of ancient Thrace, located in the region of the Thracian Chersonesos, nearly opposite to Abydos. The city was a colony of the Aeolians from Lesbos who, according to the ancient authors, founded also Sestos and Alopekonessos and other cities of the Hellespont. This was part of the Greek colonization movement of the 8th and 7th centuries BC. Later more colonists came from the Greek Ionian cities of Miletus and Clazomenae. Archaeological evidence also supports Aeolian or possibly Athenian origin of colonists.
