Eithin is Welsh in Origin.

Eithin is a Welsh nature name meaning “gorse” or “furze,” derived from Middle Welsh eithin and cognate with Irish and Scottish Gaelic aitinn, from Proto-Celtic *aitenā. In Welsh morphology, eithinen is the singular “gorse bush,” while eithin functions as a collective; as a given name, Eithin is the standard form. Pronounced EYE-thin, it evokes the spiky evergreen with vivid yellow blooms common on Welsh hillsides.

Rare as a personal name before the modern revival of Celtic nature names, Eithin is attested widely in toponyms such as Eithinog, Pen‑y‑eithin, and Waun Eithin, and in medieval and later Welsh verse where gorse signals resilience and winter brightness. Contemporary use is uncommon and largely unisex. Variants and related forms include the poetic Eithinen, the descriptive byname Eithinog (“gorsy”), and Gaelic cognate Aitinn; Anglicized usage typically preserves Eithin. The name’s meaning suggests toughness, sheltering hedges, and sunlit blossoms amid rough ground.
