Jagged Little Pill is the third studio album by Canadian singer Alanis Morissette, released on June 13, 1995, through Maverick. It was her first album to be released worldwide. It marked a stylistic departure from the dance-pop sound of her first two albums, Alanis (1991) and Now Is the Time (1992). Morissette began work on the album after moving from her hometown Ottawa to Los Angeles, where she met producer Glen Ballard. Morissette and Ballard had an instant connection and began co-writing and experimenting with sounds. The experimentation resulted in an alternative rock album that takes influence from post-grunge and pop rock, and features guitars, keyboards, drum machines, and harmonica. The lyrics touch upon themes of aggression and unsuccessful relationships, while Ballard introduced a pop sensibility to Morissette's angst. The title of the album is taken from a line in the first verse of the song "You Learn".

Jagged Little Pill was a worldwide commercial success, topping the charts in thirteen countries. With sales of over 33 million copies worldwide, it is one of the best-selling albums of all time and made Morissette the first Canadian to achieve double diamond sales. Jagged Little Pill was nominated for nine Grammy Awards, winning five, including Album of the Year, making the then 21-year-old Morissette the youngest artist to win the top honor up to that point. Rolling Stone ranked Jagged Little Pill at number 69 on its 2020 list of "The 500 Greatest Albums of All Time".

The album has been re-released twice: on October 30, 2015, in a 2-disc deluxe edition and a 4-disc collector's edition commemorating its 20th anniversary; and on June 26, 2020, in a 25th anniversary deluxe edition. An acoustic re-recording of the album was released on June 13, 2005, to mark its 10th anniversary. A musical stage production based on the album premiered at the American Repertory Theater in Cambridge on May 5, 2018; it transferred to Broadway the following year, and was nominated for 15 Tony Awards including Best Musical. A world tour celebrating the 25th anniversary of Jagged Little Pill began in early 2020 but was postponed due to the COVID-19 pandemic.
