Greatest Hits is a compilation album by American former teen idol singer Tiffany.

Although no new material was recorded, the track "Mr. Mambo" was included after it previously appeared exclusively as a b-side to "I Saw Him Standing There".

Stephen Thomas Erlewine of AllMusic gave a mixed review of the compilation, saying that although it sounded dated it was fine for "anyone wanting a collection of all of her finest moments.

"[2] Entertainment Weekly was a bit more positive in their review, saying that "although Tiffany’s music digressed into adult-ballad careerism, this set mainly proves how unrestrained her sonic youth sounded.

"[3] Fan site Tiffany.org, run by Daniel Tobias, criticized the inclusion of "Mr. Mambo" and wished other b-sides like "Can't Stop a Heartbeat" (b-side to "All This Time") and "Ruthless" (b-side to "Hold an Old Friend's Hand") were included instead.
