Noye's Fludde is a one-act opera by the British composer Benjamin Britten, intended primarily for amateur performers, particularly children. First performed on 18 June 1958 at that year's Aldeburgh Festival, it is based on the 15th-century Chester "mystery" or "miracle" play which recounts the Old Testament story of Noah's Ark. Britten specified that the opera should be staged in churches or large halls, not in a theatre.

Edward Benjamin Britten, Baron Britten was an English composer, conductor, and pianist. He was a central figure of 20th-century British music, with a range of works including opera, other vocal music, orchestral and chamber pieces. His best-known works include the opera Peter Grimes (1945), the War Requiem (1962) and the orchestral showpiece The Young Person's Guide to the Orchestra (1945).
