Gwythyr is a Welsh masculine name from Middle Welsh Gwythyr, generally understood to reflect Latin Victor, carried into Brittonic and meaning “victor, conqueror.” The element aligns with a broader Celtic preference for martial and triumphant appellations. Variant spellings include Gwythir and the anglicized Gwithyr; Victor serves as a straightforward translation-equivalent rather than a true variant.

The name is best known through Gwythyr ap Greidawl in the medieval tale Culhwch and Olwen within the Mabinogion, where he contends with Gwyn ap Nudd for the hand of Creiddylad, daughter of Lludd Llaw Eraint; Arthur decrees they must fight yearly on Calan Mai until Doomsday.
