The Good Fairy is a 1935 romantic comedy film written by Preston Sturges, based on the 1930 play A jó tündér by Ferenc Molnár as translated and adapted by Jane Hinton, which was produced on Broadway in 1931. The film was directed by William Wyler and stars Margaret Sullavan, Herbert Marshall, Frank Morgan and Reginald Owen.

Sturges' screenplay diverges significantly from the Molnár play, and later became the basis for the book of the 1951 Broadway musical Make a Wish. Sturges wrote a scene for a movie-within-the-movie, in which the leading man responds to the leading lady's impassioned pleading with the single word "Go", delivered in varying tones.
