Goodbye Mr. Mackenzie (known informally as The Mackenzies) were a Scottish 1980s and 1990s rock group formed in Bathgate, near Edinburgh, Scotland. At the band's commercial peak, the line-up consisted of Martin Metcalfe on vocals, John Duncan on guitar, Fin Wilson on bass guitar, Shirley Manson and Rona Scobie on keyboards and backing vocals, and Derek Kelly on drums.

The Mackenzies were a popular local rock group, but were unable to gain significant critical acclaim, record sales or chart positions outside of Scotland. Internationally, they are best known as the group of which Shirley Manson – the lead singer of United States alternative rock group Garbage – was once a background member.
