"Sussudio" is a pop song by Phil Collins, released as a single in February 1985. The song is also the first track on Collins' third album, No Jacket Required, released in January of the same year. The song entered frequent rotation on MTV in May, and by July 6, both the single and the album reached number one on their respective U.S. Billboard charts. The music video, which was filmed in a pub owned by Richard Branson, featured Collins playing the song to a crowd that is bored at first, but gets excited and starts dancing when Collins begins performing.

The main lyric came about as Collins was improvising lyrics to a drum machine track he had programmed, "suss-sussudio" was a working wording that scanned properly. After trying to find an alternative word to fit the rhythm, the singer decided to keep "Sussudio" as the song title and lyric. The song is about a normal crush that a schoolboy may have on a girl. The song was received mostly positively, and has been mentioned in numerous moments in pop culture.
