"You Oughta Know" is a song by Canadian singer Alanis Morissette, released as the lead single from her third studio album, Jagged Little Pill (1995) on July 6, 1995.
After releasing two studio albums, Morissette left MCA Records Canada and was introduced to manager Scott Welch. Morissette began working on new music after moving from her hometown of Ottawa to Toronto, but made little progress. In Los Angeles, she met producer Glen Ballard, with whom she wrote songs including "You Oughta Know".
"You Oughta Know" signaled Morissette's departure from bubblegum pop to alternative rock, and features guitarist Dave Navarro and bassist Flea of Red Hot Chili Peppers. It outperformed the label's expectations and received positive reviews. After the influential Los Angeles modern rock radio station KROQ-FM began playing it, the single reached the top ten in Canada, Australia and the United States. It was a multiformat hit in several US genre charts, and made the top 40 in Belgium, Iceland, the Netherlands, New Zealand, Sweden and the United Kingdom.
A music video was directed by Nick Egan. The single was added in the set list for Morissette's 1995 world tour; since then, it has been included in her albums MTV Unplugged (1999), Feast on Scraps (2002), and The Collection, as well as 1997 Grammys and the MTV Unplugged compilation albums.
It has received numerous accolades; in 1996, the single was nominated for three Grammy Awards, winning the awards for Best Rock Song and Best Female Rock Vocal Performance.
