In Greek mythology, Argeus (Ancient Greek Ἀργεύς) was a king of Argos in the Abantiad/Proetid line — son of Megapenthes and, in Pausanias' succession, father of Anaxagoras, in whose family's third the maddened women were cured and the kingdom was divided among Melampus, Bias, and Anaxagoras.

I.Son of Megapenthes
Pausanias sets Argeus between Megapenthes and Anaxagoras in the Argive king-list that descends from Proetus. His son Anaxagoras' reign is the hinge of the Melampid settlement: after the Proetid women are cured, a third of the kingdom passes to Melampus and Bias while the native third remains with Anaxagoras' house.
Other Argei — the Pelopid who marries Hegesandra at Amyclae, Licymnius' son who falls with Heracles, the Danaid bridegroom — are distinct. The atlas id is the Proetid king of Argos alone.
