Sir Alfred Butt, 1st Baronet was a British theatre impresario, Conservative politician and racehorse owner and breeder. During a fourteen-year tenure as manager of London's Palace Theatre, beginning in 1904, Butt built a theatre empire, expanding firstly with the Alhambra Theatre, Glasgow in 1910, followed by the London Victoria Palace a year later, to rival that of Edward Moss and others. He became managing director of several London West End theatres beginning in 1914, including the Adelphi Theatre, the Empire Theatre, the Gaiety Theatre and the Theatre Royal, Drury Lane, as well as theatres outside London. He continued as a theatre impresario until 1931.
