Trolls are fictional characters in J. R. R. Tolkien's Middle-earth, and feature in films and games adapted from his novels. They are portrayed as monstrously large humanoids of great strength and poor intellect. In The Hobbit, like the dwarf Alviss of Norse mythology, they must be below ground before dawn or turn to stone, whereas in The Lord of the Rings they are able to face daylight.
