In Utero is the third and final studio album by the American grunge band Nirvana, released on September 21, 1993 by DGC Records. The album's abrasive and aggressive sound was a departure from the polished production of the band's breakthrough, Nevermind, due in part to the selection of recording engineer Steve Albini. The subject matters of the song included dysfunctional family, cancer, issues of privacy, and abortion.

"Heart-Shaped Box" was the first single released from the album, followed by "All Apologies/Rape Me", which was released as a double A-side single due to the explicit nature of the latter song. Both singles topped the Billboard Modern Rock Tracks chart in the United States. "Pennyroyal Tea" was intended to be released as the third single in April 1994, but was cancelled after the death of the band's frontman, Kurt Cobain.

While In Utero did not sell as well as Nevermind, it was a commercial and critical success. The album was certified platinum by the Recording Industry Association of America by the end of 1993; it was most recently certified 5x platinum, and now ranks in the top 100 bestselling albums in the US.
