Blind Guardian is a German power metal band formed in the mid-1980s in Krefeld, West Germany. They are often credited as one of the seminal and most influential bands in the power metal and speed metal subgenres. Nine musicians have been a part of the band's line-up in its history, which has consisted of singer Hansi Kürsch, guitarists André Olbrich and Marcus Siepen, and drummer Frederik Ehmke since 2005.

Blind Guardian is a part of the German heavy metal scene that emerged in the mid-1980s. They formed in 1984 as Lucifer's Heritage by Kürsch (then also bass guitarist), Olbrich, other guitarist Markus Dörk and drummer Thomas Stauch. Dörk and Stauch both left the following year, and were replaced by Christof Theißen and Hans-Peter Frey respectively, who left as well before the end of the year. In 1987, Siepen joined and Stauch returned; under this line-up, which lasted 18 years (the longest in the band's history), the band changed their name to Blind Guardian and released their first album, Battalions of Fear, in 1988.
