Prelude and Fugue on a Theme of Vittoria is a work for solo organ composed by Benjamin Britten in 1946.
 It was commissioned for St Matthew's Church, Northampton and first performed on 21 September 1946, St Matthew's Day, three days after its composition.
 It uses a theme from a motet by the Spanish composer Vittoria, both in the prelude (where it is played repeatedly on the pedals) and as the basis for the fugue.
 The piece, which lasts about five minutes in performance, has had a mixed reception.
 One writer has noted the difficulty on finding a suitable organ on which to perform the piece, given the difficulties in finding appropriate registration to meet Britten's requirements.
 A reviewer of a concert performance in the 1960s called it "a contrived attempt to make bricks without straw", although other commentators have been more favourable about the piece.
