"Smells Like Teen Spirit" is a song by the American rock band Nirvana. It is the opening track and lead single from the band's second album, Nevermind (1991), released on DGC Records. The unexpected success of the song propelled Nevermind to the top of several albums charts at the start of 1992, an event often marked as the point when grunge entered the mainstream. It was Nirvana's biggest hit, charting high on music industry charts around the world in 1991 and 1992, and was number one on the charts in Belgium, France, New Zealand and Spain. It was met with wide critical acclaim, and described as an "anthem for apathetic kids" of Generation X. Although Nirvana grew uncomfortable with the mainstream and commercial attention the song brought to them, listeners and critics continue to praise "Smells Like Teen Spirit" as one of the greatest songs of all time.

Nirvana was an American rock band formed in Aberdeen, Washington, in 1987. Founded by lead singer and guitarist Kurt Cobain and bassist Krist Novoselic, the band went through a succession of drummers, most notably Chad Channing, before recruiting Dave Grohl in 1990. Nirvana's success popularized alternative rock, and they were often referenced as the figurehead band of Generation X. Despite a short mainstream career spanning only three years, their music maintains a popular following and continues to influence modern rock culture.
