Holy Wood (In the Shadow of the Valley of Death) is the fourth studio album by American rock band Marilyn Manson. It was released on November 11, 2000, by Nothing and Interscope Records. A rock opera concept album, it is the final installment of a triptych that also included Antichrist Superstar (1996), and marked a return to the industrial metal style of the band's earlier work, after the glam rock-influenced production of Mechanical Animals (1998). After its release, the band's eponymous vocalist said that the overarching story within the trilogy is presented in reverse chronological order: Holy Wood, therefore, begins the narrative.

Marilyn Manson is an American rock band formed by namesake lead singer Marilyn Manson and guitarist Daisy Berkowitz in Fort Lauderdale, Florida, in 1989. Originally named Marilyn Manson & the Spooky Kids, they gained a local cult following in South Florida in the early 1990s with their theatrical live performances. In 1993, they were the first act signed to Trent Reznor's Nothing Records label. Until 1996, the name of each member was created by combining the first name of a female sex symbol and the last name of a male serial killer‍—‍for example, Marilyn Monroe and Charles Manson. Their lineup has changed between many of their album releases; the eponymous lead singer is the only remaining original member.
