Melanthus

In Greek mythology, Melanthus (Ancient Greek: Μέλανθος) was a king of Messenia. He was among the descendants of Neleus (the Neleidae) expelled from Messenia, by the descendants of Heracles, as part of the legendary "Return of the Heracleidae", later associated with the supposed "Dorian invasion".

He fled to Athens, along with other of the expelled Neleidae, Alcmaeon and the sons of Paeon. Melanthus later became a king of Athens, the successor of Thymoetes, succeeded by Codrus.

Melanthus was also a shipmate of Acoetes who attempted to kidnap Dionysus.
