The King Steps Out is a 1936 American musical comedy film directed by Josef von Sternberg and starring Grace Moore, Franchot Tone and Walter Connolly. It is based on the early years of Empress Elisabeth of Austria, known as "Sisi" or "Sissi", and her courtship and marriage to Franz Joseph I of Austria, after he was initially engaged to her older sister Duchess Helene in Bavaria. The film is set from 1852 to 1854.

The script was written by Sidney Buchman, based on a theatre play called Sissys Brautfahrt by Ernst Décsey and Robert Weil aka Gustav Holm. Columbia Pictures bought the rights from Ernst Marischka in order to make the film. The lyrics for the music were by Dorothy Fields and the music by Viennese composer and violinist Fritz Kreisler. Cinematography was by Lucien Ballard and the editing by Viola Lawrence. Costume design was by the Austrian Ernst Deutsch-Dryden.

Future Broadway dancer Gwen Verdon made her movie debut doing a ballet solo at age 11, but was uncredited.

The film had only minimal influence on the later Sissi trilogy from the 1950s by Ernst Marischka starring Romy Schneider and Karlheinz Böhm.
