Frodo is the key figure in The Lord of the Rings, the fantasy trilogy by J.R.R. Tolkien first published in 1954. Frodo is the adopted son of Bilbo Baggins, and both are hobbits: a race of short, plump, cheerful beings who live in a land known as Middle Earth. Guided by the wizard Gandalf, Frodo becomes the unwilling bearer of the Ring of Power that is at the center of Tolkien's tale.

Frodo is played by Elijah Wood in the feature film trilogy of Lord of the Rings which first reached theaters in 2001.
