In Greek mythology, Argus (Ancient Greek: "Ἄργος, Argos) was the king and eponym of Argos. He was a son of Zeus and Niobe, the daughter of Phoroneus, and possibly the brother of Pelasgus. Argus succeeded to his maternal grandfather's power over Peloponnese, naming the kingdom after himself. A scholiast on Homer calls Argus son and successor of Apis.
