Lest We Forget: The Best Of is a greatest hits album by American rock band Marilyn Manson. It was released on September 28, 2004, by Interscope Records. The album was conceived by the band's eponymous vocalist as a "farewell compilation", and was originally going to feature a duet with Shirley Manson of Garbage. Upon its completion, neither singer was satisfied with the duet, and it remains unreleased. Instead, the band recorded a cover of Depeche Mode's "Personal Jesus" (1989), which became the only new track on the album and was released as a single.
