Menoetius or Menoetes (; Menoitios) meaning doomed might referred to three distinct beings:

A son of Iapetus and Clymene or Asia, and a brother of Atlas, Prometheus and Epimetheus, was killed by Zeus with a flash of lightning, in the War of the Titans, and banished to Tartarus. His name means "doomed might", deriving from the Ancient Greek words menos ("might, power") and oitos ("doom, pain"). Hesiod described Menoetius as hubristic, meaning exceedingly prideful and impetuous to the very end. From what his name suggests along with Hesiod's account, Menoetius was perhaps the Titan god of violent anger and rash action.
