"In Bloom" is a song by the American grunge band Nirvana. Written by frontman Kurt Cobain, the song addresses people outside of the underground music community who did not understand the band's message.

Nirvana made its first music video for an early version of "In Bloom" in 1990, however the song did not appear on a commercial release until the release of the group's second album, Nevermind, in 1991. "In Bloom" became the fourth and final single from the album in late 1992. It was accompanied by a new music video which parodied musical performances of 1960s variety shows.
