Margit Ingeborg Rosengren (1901–1952) was a leading Swedish operetta singer in the first half of the 20th century. After studying voice and drama, she was invited by the theatre magnate Albert Ranft to perform at Stockholm's Oscarsteatern. She made her début there in 1920 as the page Pueblo in the operetta Don César de Bazan. She subsequently performed in the Vasa and Odeon theatres and as a guest at the Royal Swedish Opera until her retirement in 1941. She also took part in revues and had a few film roles.
