In Greek mythology, Cteatus (Ancient Greek Κτέατος) is one of the Moliones — twin brothers with Eurytus, sons of Actor (or Poseidon) by Molione, and nephews of Augeas. Homer knows him as father of Amphimachus among the Epeian captains; later legend makes the twins conjoined and has Heracles kill them near Cleonae.

I.The Moliones
Cteatus and Eurytus marry Dexamenus' twin daughters Theraephone and Theronice; their sons Amphimachus and Thalpius lead Epeian ships in the Iliad. Ibycus calls them white-horsed youths born from a silver egg — a Dioscuri-like twin birth. Some authors say they were conjoined (one body, two heads, four arms and legs), though Homer does not.
They fight for Neleus against the Pylians and later command Augeas' army against Heracles; after a truce they attack him and he kills them on the road to the Isthmian games. Pausanias saw their tomb at Cleonae.
II.Homonym care
The atlas keeps cteatus-epeian beside eurytus-epeian and the mother-node molione-epeian. Cteatus is not an unrelated Trojan or Argive namesake; Eurytus of Oechalia is a different hero.
