Decapitated is a Polish death metal band formed in Krosno in 1996. The group is composed of guitarist, founder and composer Wacław "Vogg" Kiełtyka, vocalist Rafał Piotrowski, bassist Paweł Pasek and drummer James Stewart. Decapitated are recognized as one of the death metal's most widely respected bands and one of the finest exponents of technical death metal. The band earned an international fan base in the underground music community and became an innovating act in the modern death metal genre.

Vogg and his younger brother, drummer Witold "Vitek" Kiełtyka, founded Decapitated along with vocalist Wojciech "Sauron" Wąsowicz in their mid-teens, joined by bassist Marcin "Martin" Rygiel one year later. After releasing two demos, the band signed with Wicked World (subsidiary of Earache Records) and released their debut album Winds of Creation in 2000. In 2002 and 2004 the band released the albums Nihility and The Negation, respectively. The band's fourth album, Organic Hallucinosis was released in 2006 with vocalist Adrian "Covan" Kowanek, who had replaced Wąsowicz the year before.

In late 2007, the band was involved in an automobile accident. Vitek died at the age of 23 on November 2, 2007, from the injuries he suffered from the accident; Covan survived, but he slipped into a coma as a result. After a period of disbandment, Vogg reformed Decapitated in 2009 and the band has released four more studio albums since then: Carnival Is Forever (2011), Blood Mantra (2014), Anticult (2017) and Cancer Culture (2022). Alternative Press described Decapitated as remaining one of "death metal's elite" bands.
