Arwen is a female name invented by J. R. R. Tolkien for his Middle-earth legendarium. It appears in the fictional language Sindarin, composed of the elements *ara- ("noble") and gwen ("maiden"), thus meaning "noble maiden". The name is famously borne by the character Arwen Undómiel, the half-elven daughter of Elrond and the wife of Aragorn in The Lord of the Rings and The Silmarillion.
