"You Oughta Know" is a song written by Alanis Morissette and Glen Ballard, and produced by Ballard for Morissette's third album Jagged Little Pill (1995).
The song reached number one on Billboard magazine's Modern Rock Tracks chart in the U.S. and charted at number four in Australia and number twenty-two in the United Kingdom. Launching Morissette's career, and the album, Jagged Little Pill, to the top, the coarse language, violent revenge scenarios, and piercing vocals were a jolt to mainstream pop music. "You Oughta Know" was not eligible for the U.S. Billboard Hot 100 in 1995 because a retail single was not released, but it reached number thirteen on the Hot 100 Airplay chart and the top ten on the Top 40 Mainstream chart. A live version of the song, recorded at the 1996 Grammy Awards ceremony on February 28, was a B-side on the retail single for "You Learn", and Billboard credited the single's Hot 100 number-six peak position to "You Learn"/"You Oughta Know".
Red Hot Chili Peppers band members Flea and Dave Navarro performed bass and guitar, respectively, on the song. In 2010, Navarro reflected upon the recording, stating that: "Flea and I did that song together in the studio. It was already written with different instrumentation and we were asked to kind of re-write the music; a lot like a re-mix. The structure of the song was in place but there were no guide tracks, we just had the vocal to work from. It was just a good time and we basically jammed until we found something we were both happy with. Alanis was happy too."
Matt Laug played drums on the 1995 release of "You Oughta Know". Morissette has reimagined the song numerous times, most recently on her 2005 album Jagged Little Pill Acoustic, which featured mellowed vocals and chord progressions; the lyrics, however, were not softened.
It won two Grammy Awards, Best Rock Song and Best Female Rock Vocal Performance. Also was nominated for Song of the Year, losing to "Kiss from a Rose" by Seal, at the Grammy Awards of 1996.
"You Oughta Know" was ranked #12 on VH1's 100 Greatest Songs of the 90's in December 2007.
