Disbelief - sometimes decapitalised to 'disbelief' - is a German Metal Band. Their music combines death metal with doom metal and post-hardcore.

The band was formed in 1990, but did not become one solid line-up for several years. They began with Karsten Jäger, Oliver Lenz, and drummer Markus Gnap, with guitarist/bassist Denis Musiol joining later. They released their first demo the following year. After two more demo tapes , five years, and the replacement of Gnap and Musiol with Tommy Fritsch, Jochen Trunk, and Kai Bergerin, they released their self-titled album in 1997. Their second album, Infected, was released in 1998. A year later, they replaced Fritsch with Jan-Dirk Löffler and received a new recording contract from Massacre Records. After a few more albums, they became signed to Nuclear Blast, which distributed their 2004 record Spreading the Rage to North America and helped them to gain a wider fanbase. After reinstating Fritsch into the band, they released 66Sick in 2005, also in the Americas. Lenz left the band in late 2006, and has not yet been replaced; however, the band's seventh album, Navigator, is still slated for release in late February.
