Gyas, a character in Virgil's Aeneid, features most extensively as one of the captains in the boat race in Book 5. He also appears (briefly) in Books 1 and 12. He was claimed as the eponymous ancestor of the Gegania gens, a patrician family of the Roman Republic.

Gyas is introduced to the reader after Aeneas has landed on the coast of Libya, after the storm dispersed and, he fears, wrecked his fleet. "Intrepid Gyas" is one of the captains whose presumed death he mourns (Aeneid 1.222).

Gyas, through his "extraordinary" and "ill considered" action, forces himself to take up two roles: captain and helmsman. In doing so, he prefigures Aeneas, who will have to do the same thing at the end of Book 5, after Palinurus falls overboard and drowns. According to Joseph Farrell, the comparison favors Aeneas. The swimming ability of "old man" Menoetes to swim to shore fully clothed, and without the assistance of a magical veil, contrasts with Odysseus's swim to shore and avoidance of the sort of rocks at Phaeacia that Menoetes clambered up onto unaided. Gyas was considered the eponymous ancestor of the Gegania gens (the link was made by Maurus Servius Honoratus, a fifth century grammarian and commentator of Virgil), but Virgil lists the other three captains (Mnestheus, Sergestus, Cloanthus) along with the families they supposedly founded (the Memmia gens, the Sergia gens, and the Cluentians, respectively), the Gegania, which would have been much less familiar to Virgil's audience than the other families, get no such credit, which John Conington found "singular". David Ross, professor of classics at the University of Michigan, also noted Gyas was not directly connected to a gens, and also characterized the description of the Chimaera as "decidedly odd", seeming to be "an aircraft carrier, racing against destroyers". Joseph Addison wrote in issue 279 of The Spectator that "Sentiments which raise laughter can very seldom be admitted with any decency into an heroic poem [ ] I remember but one laugh in the whole Aeneid, which rises in the fifth book upon Menoetes, where he is represented as thrown overboard, and drying himself upon a rock.". David Ross observed that it is, however, "the laughter of mockery and derision". Professor of Latin at University College London M. M. Willcock concurred that it is "insensitive" and that "[t]o laugh at the unmerited misfortune of another human being is not the highest moral reaction", observing that Menoetes had done nothing deserving of such a reaction from spectators. Addison's recollection notwithstanding, a second instance of the same mocking laughter occurs when Sergestus brings his boat in.

Through the word "clavus" meaning both tiller and club, the "huge" namesake in 10.317–322 who lays his foes low with a club that belongs to Hercules is linked by scholars to the ship's captain.

In Book 12.460, Gyas beheads Ufens (Aeneid 12.460).
