Peter Lindgren (born March 6, 1973) is a Swedish guitarist and songwriter. He is best known as the guitarist of Swedish progressive metal band Opeth. He joined the band in 1991 to play bass for a show; however, he ended up staying and switching to guitars. Lindgren shares Opeth's guitar and songwriting duties with vocalist Mikael Åkerfeldt.

Although both play solos, Lindgren's solos are somewhat more melodic and technical than Åkerfeldt's. This can be heard on the songs Deliverance from the album Deliverance, and Beneath the Mire from Ghost Reveries. The decision of who plays which leads are decided by Åkerfeldt's vocal duties and whoever wants any particular solo the most. If Åkerfeldt is having trouble with a solo, he will hand it over to Peter, and vice versa.

In May of 2007, Peter announced that he would no longer be playing music with Opeth he was replaced by Fredrik Åkesson.
