Geppetto ( jə-PET-oh; Italian: [dʒepˈpetto]) is a fictional character in the 1883 Italian novel The Adventures of Pinocchio by Carlo Collodi. Geppetto is an elderly, impoverished woodcarver and the creator (and thus 'father') of Pinocchio. He wears a yellow wig resembling cornmeal mush (called polendina), and consequently his neighbors call him "Polendina" to annoy him. The name Geppetto is a Tuscan diminutive of the name Giuseppe (Italian for Joseph).
