"Don't!" is a song by Canadian singer Shania Twain. It was the second single released from her 2004 Greatest Hits album (not to be confused with the Billy Currington song of the same title). The song was written by Twain and then-husband Mutt Lange. "Don't!" underperformed on most charts, mostly due to no promotion by Shania and very little by the label. The highest it made was number ten airplay in Canada. The song was also included under the end credits of the 2005 film An Unfinished Life, and in the Brazilian soap opera América.
