Archias, son of Anaxidotos (Ancient Greek: Ἀρχίας Ἀναξιδότου Πελλαῖος) was a quasi-mythological Corinthian citizen and founder (oekist) of the colony of Syracuse in Sicily, Magna Graecia.
Finding that "no fair means or persuasion" prevailed upon the youth, Archias made plans to kidnap him.
Under the guise of inviting himself to Melissus' house in order to take part in a feast, Archias and his accomplices laid hands on the boy and attempted to spirit him away.
In return he climbed to the top of Poseidon's temple, invoked the god's wrath as vengeance for his son's murder and threw himself onto the rocks.
Archias went into voluntary exile, and led a group of Corinthians into Sicily where they established the colony of Syracuse.
