Powerwolf (often stylized in all caps) is a German power metal band founded in 2003 in Saarbrücken by members of Red Aim. The band consists of vocalist Karsten Brill as "Attila Dorn", lead guitarist Benjamin Buss as "Matthew Greywolf", bassist/rhythm guitarist David Vogt as "Charles Greywolf", keyboardist Christian Jost as "Falk Maria Schlegel" and drummer Roel van Helden. The group uses religious themes and images, contrary to traditional power metal music, as well as corpse paint, gothic-tinged compositions and songs about werewolf and vampire legends.

They released their debut album, Return in Bloodred, in 2005. Their second album, Lupus Dei, was released in 2007. The band entered the official German charts for the first time in 2009 with their third album, Bible of the Beast. Shortly after its release, their first drummer Stefan Gemballa (stage name Stéfane Funèbre) left the band. He was replaced by Tom Diener, who was replaced in 2011 by Roel van Helden. In the same year, the band released their fourth album, Blood of the Saints. In 2012, Powerwolf signed with Napalm Records and released Preachers of the Night in 2013. It has debuted at No. 1 in Germany. Their sixth album, Blessed & Possessed, released in 2015, was certified gold in the Czech Republic. Their seventh album, The Sacrament of Sin, was released in 2018. Their eighth album, Call of the Wild, was released in 2021. Their ninth album, Interludium, was released in 2023.

Powerwolf has embarked on several tours, with a majority of their tour dates taking place inside of Europe. They also change their costumes for every album. Over the years, a theme has developed which personifies the band members as werewolves, leading fans to refer to the band affectionately as "The Wolves".
