Arestor (Greek: Ἀρέστωρ) son of Iasus, is a character from Greek mythology. He is the father of Argus Panoptes, who is therefore called Arestorides (Apollod. ii.1.3, Apollon. Rhod. i.112, Ov. Met. i.624). According to Pausanias (ii.16.3), Arestor was the husband of Mycene, the daughter of Inachus, from whom the town of Mycenae derived its name.
