Cresphontes

In Greek mythology, Cresphontes (; Ancient Greek: Κρεσφόντης) was a son of Aristomachus, husband of Merope, father of Aepytus and brother of Temenus and Aristodemus. He was a great-great-grandson of Heracles and helped lead the fifth and final attack on Mycenae in the Peloponnesus. He became king of Messene.

Cresphontes and his brothers complained to the oracle that its instructions had proved fatal to those who had followed them (the oracle had told Hyllus to attack through the narrow passage when the third fruit was ripe). They received the answer that by the "third fruit" the "third generation" was meant, and that the "narrow passage" was not the isthmus of Corinth, but the straits of Rhium. They accordingly built a fleet at Naupactus, but before they set sail, Aristodemus was struck by lightning (or shot by Apollo) and the fleet destroyed, because one of the Heraclidae had slain an Acarnanian soothsayer.
