In Greek mythology, Armenus or Armenius () was one of the Argonauts, though he was obscure and rarely discussed.
He was believed to have been a native of Rhodes or of Armenion in Thessaly, and to have settled in the country which was called, after him, Armenia.Strabo, Geographica 11.4.8.Justin 42.2Stephanus of Byzantium, Ethnica s.v. Ἀρμενία
