Dookie is the third studio album by the American rock band Green Day, released on February 1, 1994, by Reprise Records. The band's major label debut and first collaboration with producer Rob Cavallo, it was recorded in late summer 1993 at Fantasy Studios in Berkeley, California. Written mostly by the singer and guitarist Billie Joe Armstrong, the album is largely based on his personal experiences and includes themes such as boredom, anxiety, relationships, and sexuality. It was promoted with four singles: "Longview", "Basket Case", a re-recorded version of "Welcome to Paradise" (which originally appeared on the band's second studio album, 1991's Kerplunk), and "When I Come Around".

After several years of grunge's dominance in popular music, Dookie brought a livelier, more melodic rock sound to the mainstream and propelled Green Day to worldwide fame. Considered one of the defining albums of the 1990s and of punk rock in general, it was also pivotal in solidifying the genre's mainstream popularity. Its influence continued into the new millennium and beyond, being cited as an inspiration by many punk rock and pop-punk bands, as well as artists from other genres.

Dookie received critical acclaim upon its release, although some early fans accused the band of being sellouts for leaving its independent label (Lookout! Records) and embracing a more polished sound. The record won a Grammy Award for Best Alternative Album at the 37th Annual Grammy Awards in 1995. It was a worldwide success, peaking at number two on the Billboard 200 in the United States and reaching top ten positions in several other countries. Dookie was later certified double diamond (20-times platinum) by the Recording Industry Association of America (RIAA). It has sold over 20 million copies worldwide, making it the band's best-selling album and one of the best-selling albums of all time. It has been labeled by critics and journalists as one of the greatest albums of the 1990s and one of the greatest punk rock and pop-punk albums of all time. Rolling Stone placed Dookie on all four iterations of its "The 500 Greatest Albums of All Time" list, and at number 1 on its "The 50 Greatest Pop-Punk Albums" list in 2017. In 2024, the album was selected for preservation in the United States National Recording Registry by the Library of Congress as being "culturally, historically, or aesthetically significant".
