This is a list of Viking metal bands. Viking metal is a style of heavy metal music with origins in black metal and Nordic folk music, characterized by a lyrical and thematic focus on Norse mythology, Norse paganism, and the Viking Age. Viking metal is quite diverse as a musical style, to the point where some consider it more a cross-genre term than genre, but it is typically manifested as black metal with influences from Nordic folk music. Common traits include a slow-paced and heavy riffing style, anthemic choruses, use of both clean and harsh vocals, a reliance on folk instrumentation, and often the use of keyboards for atmospheric effect.
