"(You're the) Devil in Disguise" is a 1963 single by Elvis Presley. It was written by Bill Giant, Bernie Baum and Florence Kaye and was published by Elvis Presley Music in June 1963. The song peaked at No. 3 in the US on the Billboard singles chart on August 10, 1963, and No. 9 on the Billboard Rhythm and Blues singles chart, becoming his last top ten single on those charts. The single was certified "Gold" by the RIAA for sales in excess of 500,000 units in the US. The song also topped Japan's Utamatic record chart in the fall of 1963. In June 1963, when the song was debuted to a British audience on the BBC television show Juke Box Jury, celebrity guest John Lennon voted the song "a miss" stating on the new song that Elvis Presley was "like Bing Crosby now". The song went on to reach No. 1 in the UK for a single week.
