Marie Dubas (3 September 1894 – 21 February 1972) was a French music-hall singer, diseuse and comedian. Born in Paris, France, Marie Dubas began her career as a stage actress but became famous as a singer.

Using the great Yvette Guilbert as her model, Dubas started singing in the small cabarets of Montmartre mixing comedy into her routine. She earned a following that led to offers to perform in Parisian operettas and musicals and during the 1920s and 1930s, starred at such places as the Casino de Paris and Bobino, the great music hall in Montparnasse. Her most famous song, Mon légionnaire, was written by Raymond Asso and recorded in 1936.
