Gwyn is Welsh in Origin.

Gwyn is a Welsh given name stemming from the adjective gwyn, meaning “white, fair, blessed,” with a traditional masculine use and the pronunciation GWIN. The feminine counterpart in Welsh is Gwen, while in Breton and Cornish the same Celtic root appears as gwenn/gwyn with the same sense of brightness or holiness.

Documented in medieval Wales, the name is borne in legend by Gwyn ap Nudd, ruler of Annwn and leader of the wild hunt, helping anchor the name in native mythology. Usage persisted in Wales and later spread through the British Isles and the diaspora; modern English sometimes treats Gwyn as unisex. Surname forms such as Gwynn, Gwynne, and Wynn arise from the given name. Common variants include Gwynn, Gwynne, Wyn, and Wynne; related Welsh names built on the element include Gwyneth, Gwynfor, and Gwyneira, while the feminine parallel line yields Gwen, Gwenno, and Gwenllian.
