'Californication' is the seventh studio album by Red Hot Chili Peppers. First released on June 8, 1999, on Warner Bros. Records, and produced by Rick Rubin, the album cemented the band into the lexicon of rock history.

The album marked the return of John Frusciante, who had previously appeared on 'Mother's Milk' and 'Blood Sugar Sex Magik,' to replace Dave Navarro as the band's guitarist. Frusciante's return was credited with changing the band's sound altogether, producing a notable shift in style from the music recorded with Navarro. The album's subject material incorporated various sexual innuendos commonly associated with the band, but also contained more varied themes than previous outings, including lust, death, contemplations of suicide, California, drugs, globalization, and travel.

'Californication' is the Chili Peppers' most commercially successful studio release internationally, with over 15 million copies sold worldwide, and more than 5 million in the United States alone. The record produced several hits for the band, including "Otherside," "Californication," and the Grammy Award-winning "Scar Tissue."
