Doctrine is the sixth studio album by Dutch death metal band Pestilence, which was released on April 24, 2011. The album was recorded and mixed at Woodshed Studio in southern Germany with engineer Victor "V.Santura" Bullok. The artwork was designed by Marko Saarelainen. The album represents a second release by the reformed Pestilence, with two new members: Yuma van Eekelen and Jeroen Paul Thesseling, who was a member of the band during the Spheres era. Technically, the album is an experimentation with very low tunings, with Mameli and Uterwijk playing on 8-string guitars with standard tuning, and Thesseling playing a 7-string fretless bass tuned in F#.
