Maurice Yvain (12 February 1891 – 27 July 1965) was a French composer, noted for his operettas of the 1920s and 1930s, some of which were written for Mistinguett, at one time the best-paid female entertainer in the world. In the 1930s and 1940s he became a major success in the United States and several of his pieces appeared in the famous Ziegfeld Follies on Broadway.
