In Greek mythology, Argus (Argos) son of Arestor is the shipwright who, with Athena's guidance, built the fifty-oared Argo for Jason's quest of the Golden Fleece. Apollonius Rhodius has Athena teach him at Pagasae and fit a speaking oak from Dodona in the prow. Distinct from Argus Panoptes, Odysseus's dog Argos, Colchian Argus son of Phrixus, and other Argus/Argos figures.

I.Building the Argo
Apollonius makes Argus son of Arestor Athena's pupil in constructing the vessel in Thessaly near Pelion / Pagasae. Apollodorus describes a fifty-oared ship — a mythic penteconter — whose crew the Argonauts themselves supplied. A sacred Dodona oak in the prow spoke oracles; Hera protected the voyage.
Hyginus also knows an Argive Argus (son of Polybus and Argia, or of Danaus) as builder; traditions vary on whether the shipwright sailed with the crew. The ship was later dedicated to Poseidon at the Isthmus of Corinth.
II.Homonym care
Ancient and modern writers sometimes conflate the Arestorid shipwright with Argus son of Phrixus and Chalciope at Colchis (atlas id argus-colchis). The atlas keeps them apart: argus-arestor is the builder; argus-panoptes the hundred-eyed watchman; argos-dog Odysseus's hound.
