Marguerite Bériza (1880 – 1970) was a French opera singer who had an active international career during the first half of the 20th century. She began her career as a mezzo-soprano at the Opéra-Comique in 1900; ultimately transitioning into the leading soprano repertoire at that theatre in 1912. She performed extensively in the United States from 1914–1917 and was also heard as a guest artist at theatres in the French provinces, Monaco, Portugal, and Switzerland during her career. In 1924 she founded her own opera company in Paris with whom she actively performed up until 1930.
