Nevermind is the second studio album by the American rock band Nirvana, released on September 24, 1991. Produced by Butch Vig, Nevermind was the group's first release on DGC Records. Frontman Kurt Cobain sought to make music outside the restrictive confines of the Seattle grunge scene, drawing influence from groups such as the Pixies and their use of song volume dynamics.

Despite low commercial expectations by the band and its record label, Nevermind became a surprise success in late 1991, largely due to the popularity of its first single, "Smells Like Teen Spirit". By January 1992, it had replaced Michael Jackson's album Dangerous at number one on the Billboard charts. The Recording Industry Association of America has certified the album Diamond (over 10 million copies shipped), and the album has sold over 30 million copies worldwide. Nevermind was responsible for bringing alternative rock to a large mainstream audience, and critics subsequently regarded it as one of the best rock albums of all time.
