Dookie (stylized as dookie) is the third studio album and the major label debut by American rock band Green Day, released on February 1, 1994 by Reprise Records. The band's first collaboration with producer Rob Cavallo, it was recorded in late 1993 at Fantasy Studios in Berkeley, California. Written mostly by frontman Billie Joe Armstrong, the album is heavily based around his personal experiences, with themes such as boredom, anxiety, relationships, and sexuality. The album was promoted with five singles: "Longview", "Basket Case", a re-recorded version of "Welcome to Paradise" (originally on their Kerplunk album), "When I Come Around", and the radio-only "She". "All by Myself" is a hidden track performed by drummer Tré Cool.

Dookie received critical acclaim upon its release, and won the band a Grammy Award for Best Alternative Album in 1995. It was also a worldwide success, reaching number two in the United States and the top five in several other countries; it is credited with bringing punk rock to mainstream popularity, and propelling Green Day to worldwide fame. It was later certified diamond by the RIAA, and has sold close to 20 million copies worldwide, making it the band's best-selling album and one of the best-selling albums worldwide. In 2003, Rolling Stone placed Dookie at number 193 on their list of the "500 Greatest Albums of All Time", maintaining the rating in a 2012 revised list. In 2020, Rolling Stone re-ranked the album at number 375 on another revised list. Regarding its legacy, Dookie has been labeled by critics as one of the greatest punk rock albums of all time.
