In Greek mythology, Menoetius was a second-generation Titan, son of Iapetus and Clymene (or Asia), brother of Atlas, Prometheus, and Epimetheus. Hesiod has Zeus strike him with a thunderbolt for hubris and send him to Erebus; Apollodorus places the blow in the Titanomachy and hurls him to Tartarus. Distinct from Menoetes the underworld herdsman and from Menoetius of Opus, father of Patroclus.

I.The hubristic Titan
Hesiod names Menoetius among Iapetus's sons by the Oceanid Clymene: Zeus smites the "outrageous" brother with a smoking bolt and casts him to Erebus for mad presumption. Apollodorus makes the mother Asia and sets the punishment on the battlefield of the Titanomachy, with Tartarus as the pit. From the name and Hesiod's epithets he is sometimes read as a Titan of violent anger and rash action — a short dossier beside his more famous brothers.
No extensive cult or later romance attaches to him; he exists chiefly as the fourth Iapetid whose pride meets lightning.
II.Homonyms
The atlas id menoetius is the Titan, not Menoetes son of Keuthonymos who wrestles Heracles in Hades, nor the Opuntian Argonaut Menoetius, father of Patroclus — both share the name but belong to different generations and stories.
