Joseph Farren Soutar (17 February 1870 – 23 January 1962) (billed as Farren Soutar) was an English actor and singer who became known for his performances in Edwardian Musical Comedies in the West End and on Broadway. Later he acted in some serious plays. His mother was Nellie Farren, the famous principal boy in Victorian burlesque.
Born in Greenwich in London, he was the son of the actor, stage manager, and director Robert Soutar and the actress and singer Nellie Farren, known for her roles as the "principal boy" in musical burlesques at the Gaiety Theatre. His older brother was Henry Robert Soutar (1868–1928). A boyhood friend (and with whom he was later to work on the 1934 film The Iron Duke) was George Arliss, for whom Soutar found his first acting job in 1886.
