Blue Öyster Cult (/ˈɔɪ.stər/ OY-stər; often abbreviated BÖC or BOC) is an American rock band formed in Stony Brook, New York, in 1967, best known for the singles "(Don't Fear) The Reaper", "Burnin' for You", and "Godzilla". They have sold 25 million records worldwide, including seven million in the United States alone. The band's music videos, especially "Burnin' for You", received heavy rotation on MTV when the music television network premiered in 1981, cementing the band's contribution to the development and success of the music video in modern popular culture.

Blue Öyster Cult's longest-lasting and most commercially successful lineup included Donald "Buck Dharma" Roeser (lead guitar, vocals), Eric Bloom (lead vocals, "stun guitar"), Allen Lanier (keyboards, rhythm guitar, backing vocals), Joe Bouchard (bass, vocals), and Albert Bouchard (drums, percussion, vocals). The band's current lineup still includes Bloom and Roeser, in addition to Danny Miranda (bass, backing vocals), Richie Castellano (keyboards, rhythm guitar, backing vocals), and Jules Radino (drums, percussion). The duo of the band's manager Sandy Pearlman and rock critic Richard Meltzer, who also met at Stony Brook University, played a key role in writing many of the band's lyrics.
