Edward Geoffrey Toye (17 February 1889 – 11 June 1942), known as Geoffrey Toye, was an English conductor, composer and opera producer.
He is best remembered as a musical director of the D'Oyly Carte Opera Company and for his association with Sadler's Wells Theatre. One of his ballets, The Haunted Ballroom (1934), became popular and was revived several times, and the new overture that he prepared for Gilbert and Sullivan's Ruddigore in 1919 became the standard version.
