If I Could Turn Back Time: Cher's Greatest Hits is the fourth U.S. compilation album by American singer-actress Cher, released on March 9, 1999 by Geffen. In January 2000, the album was certified Gold by the RIAA for selling more than 500,000 copies in the US. Billboard stated in November 2011 that the album has sold 955,000 copies in the US.
The album was released in USA and Canada in March 1999 by Cher's former record company the Geffen records. It peaked at #57 on the US Billboard 200 album chart and #40 on the Canadian album chart. As it was made available as an import in some countries, the album peaked at #2 on the Danish albums chart in February of 1999, being held from the top spot by Cher's current studio album Believe.
The album was originally released with a remix of "Don't Come Cryin' To Me," a track that was recorded during the Heart of Stone album sessions, but the track was later removed per Cher's personal request. In November of the same year, Cher's current record label Warner Brothers released the compilation The Greatest Hits outside North America.
