Cultösaurus Erectus is the seventh studio album by American rock band Blue Öyster Cult, released in June 1980. Following an experiment with a more commercial sound on the album Mirrors, this recording marked a return to the band's earlier, heavier sound. It also represents the band's first collaboration with British producer Martin Birch, who would also produce the band's next album Fire of Unknown Origin a year later. While the album did sell more than its predecessor, it stalled at Gold status. However, during this time, Blue Öyster Cult was still filling large venues. The tour promoting Cultösaurus Erectus found the band co-headlining sports arenas in the United States with Black Sabbath as part of the Black and Blue Tour. The album cover features the central part of the painting Behemoth's World by British artist Richard Clifton-Dey.
