Peregrin Took, commonly known simply as Pippin, is a fictional character from J. R. R. Tolkien's fantasy novel The Lord of the Rings. He is closely tied with his friend and cousin, Merry Brandybuck, and the two are together during most of the story. Pippin and Merry are introduced as a pair of young hobbits of the Shire who become ensnared in their friend Frodo Baggins's quest to destroy the One Ring. Pippin joins the Fellowship of the Ring. He and Merry become separated from the rest of the group at the breaking of the Fellowship and spend much of The Two Towers with their own story line. Impetuous and curious, Pippin enlists as a soldier in the army of Gondor and fights in the Battle of the Morannon. With the other hobbits, he returns home, helps to lead the Scouring of the Shire, and becomes Thain or hereditary leader of the land.
