"Rudy" is a pop rock ballad written by Dennis Frederiksen, Henri Belolo, Howie Epstein, Jacques Morali, Jimmy Hunter and Mark Maierhoffer. Produced by John Farrar and under the label of Columbia Records, in May 6, 1982, it was covered by American singer-actress Cher, who released it as the lead single from her seventeenth studio album. The song also appears on the greatest hits compilation The Very Best of Cher (2003) as fourteenth track of the International version of the album.
No music video was ever made for the song, which did not help the song's chart fortunes.
AllMusic retrospectively described the single as a girl-group-styled song, noting how it and another track stood out on the album.
