Barrow-wights are wraith-like creatures in J. R. R. Tolkien's world of Middle-earth. In The Lord of the Rings, the four hobbits are trapped by a barrow-wight, and are lucky to escape with their lives; but they gain ancient swords of Westernesse for their quest.
Tolkien derived the idea of barrow-wights from Norse mythology, where heroes of several Sagas battle undead beings known as draugrs. Scholars have noted a resemblance, too, between the breaking of the barrow-wight's spell and the final battle in Beowulf, where the dragon's barrow is entered and the treasure released from its spell. Barrow-wights do not appear in Peter Jackson's film trilogy, but they do feature in computer games based on Tolkien's Middle-earth.
