Peter Lindgren (born March 6, 1973) is a Swedish musician and songwriter. He is best known as the former guitarist of Swedish progressive death metal band Opeth. In 1991 he joined Opeth to play bass for a show, but ended up staying and switching to guitars.
Lindgren played approximately half of Opeth's lead guitar sections. As explained in "The Making of Deliverance and Damnation" on Opeth's live DVD Lamentations, lead-playing duties were based on ease of Mikael Åkerfeldt's vocal delivery and which of the two might want a given solo more. If Åkerfeldt was having trouble with a solo, he would hand it over to Lindgren, and vice versa. In March 2004, Peter and Mikael Åkerfeldt were both ranked #42 out of the 100 Greatest Heavy Metal Guitarists of all time by Guitar World.
Lindgren holds degrees in physics and philosophy.
