Fredegar Bolger, also referred to by his friends as Fatty, is a fictional character in J. R. R. Tolkien's Middle-earth world, appearing in The Lord of the Rings. Fredegar was a Hobbit from the Shire, and friend to Frodo Baggins.
He was one in the small group knowing about the One Ring and Frodo's departure for Rivendell. When the other hobbits left the Shire, Fredegar stayed behind in Crickhollow to prevent the knownledge of Frodo's departure spreading for as long as possible.
During Saruman's rule of the Shire, Fredegar led a small resistance group fighting against the Ruffians. He was captured and imprisoned, but later freed by his returning friends during the Scouring of the Shire.
