Viola Tree (17 July 1884 – 15 November 1938) was an English actress, singer, playwright and author. Daughter of the actor Herbert Beerbohm Tree, she made many of her early appearances with his company at His Majesty's Theatre. Later she appeared in opera, variety, straight theatre and film. Tree made her London debut in 1904 as Viola in Twelfth Night, and for the next four years she appeared in her father's productions at His Majesty's Theatre, often in Shakespeare roles. She yearned to have an operatic career, and studied in Milan, but sang only two opera roles; she then resumed her career in plays and in variety. In 1919, she became manager of the Aldwych Theatre, while continuing her acting career. In 1930–31 she played on Broadway and on tour in drama and appeared in the Ziegfeld Follies. In London in the 1930s, she played in comedies and tried her hand at directing. Her last West End role was in The Melody that Got Lost in 1938. She also appeared in four films between 1920 and 1938, wrote two plays and several books, including a novel and a book of etiquette.
