Believe is the second studio album by American heavy metal band Disturbed, released on September 17, 2002 via Reprise Records. Produced by the band and Johnny K, it focuses heavily on religious and spiritual themes inspired by recent tragedies. With greater emphases on melodic dynamics, it also demonstrates a broadening in the band's musical range compared to their 2000 debut The Sickness. Believe was the last studio album to feature original bassist Steve "Fuzz" Kmak before he was fired from the band in 2003.
