"Rain on Your Parade" is a song by Welsh singer Duffy from the deluxe version of her debut studio album Rockferry (2008). It was released as the lead and only single from the deluxe album worldwide on 9 November 2008. The song was written by Duffy and Rockferry collaborator Steve Booker and produced by Booker. It is an up-tempo pop song in which Duffy uses an idiom for ruining her lover and their intentions. The song marked a departure from the down-tempo soul and balladry of the original version of Rockferry, incorporating elements of R&B and soul. It received positive reviews from critics, with many complimenting Duffy's vocals. Musically, the song bears a striking resemblance to James Bond songs, making notable use of strings. It was called a "big, retro-sounding pop-soul number".
