"Lunchbox" is a song by American rock band Marilyn Manson. It was released as the second single from their debut album, Portrait of an American Family (1994). A heavy metal song that features elements of death metal, industrial music and punk rock, "Lunchbox" was written by the band's eponymous vocalist, Daisy Berkowitz, and Gidget Gein, and produced by Manson with Trent Reznor. According to Berkowitz, the track was written as the frontman's plea to be left alone; it was also inspired by a time where Manson defended himself from bullies with a Kiss lunchbox. The track features elements of "Fire" (1968) performed by Arthur Brown, a musician who influenced the band.
