Elfwine

In J. R. R. Tolkien's Middle-earth legendarium, Elfwine was the nineteenth King of Rohan.

Elfwine was the first son of Éomer Éadig (King of Rohan) and Lothíriel (daughter of Prince Imrahil of Dol Amroth).

As Elfwine ruled in the Fourth Age after the Red Book of Westmarch had been written, not much is known about him, but it can be speculated that as an ally of Gondor his was a rule of peace in which the Rohirrim recovered from the War of the Ring. He became king in the year 63 of the Fourth Age, and ruled long after.
