Odette Myrtil (born Odette Laure Clotilde Quignarde; June 28, 1898 – November 18, 1978) was a French-born American actress, singer, and violinist. She began her career as a violinist on the vaudeville stage in Paris at 14. She expanded into acting and singing and had her first major success at 18 on the London stage in the 1916 musical revue The Bing Boys Are Here. She was a staple in Broadway productions from 1924 to 1932, after which she returned only periodically to Broadway through 1960. She also appeared on the stages of Chicago, London, Los Angeles, and Paris several times during her career.

From 1923 to 1972, Myrtil appeared as an actress in a total of 28 feature films, most of which were made from the mid-1930s through the mid-1950s. Not a leading lady on camera, she specialized in character roles and was often used for her gifts as a singer. She made only one television appearance during her career: in the Studio One in Hollywood 1953 episode "The Paris Feeling". She worked as a costume designer for nine motion pictures from 1944 to 1950.
