The Blue Fairy is a supporting character in the 1940 Disney animated feature film Pinocchio.

She is a magical being who, fulfilling Geppetto's wish, transformsPinocchio into a living being and later into a real boy. She also aids Pinocchio and Jiminy Cricket throughout their adventures, both directly and from afar.

One of only two female characters in the film (the other being Cleo), she is nevertheless one of the most powerful characters in the cast; it is she who initially grants Pinocchio life and who ultimately decides whether or not he should become a real boy
