Fallen is the debut studio album by American rock band Evanescence, released on March 4, 2003 by Wind-up Records. Co-founders singer and pianist Amy Lee and guitarist Ben Moody began writing and recording songs as Evanescence in 1994, and after releasing two EPs and a demo CD, they signed to Wind-up in January 2001. Several of the songs from their earlier independent releases feature on Fallen. The album was recorded between August and December 2002 in several studios in California. It is Evanescence's only studio album to feature Moody, who left the band in October 2003.

The album yielded four singles: "Bring Me to Life", "Going Under", "My Immortal", and "Everybody's Fool". "Bring Me to Life" and "My Immortal" charted in the top 10 of over 10 countries, including the US, UK and Australia. Fallen is Evanescence's most commercially successful album to date, selling 10 million copies in the US and over 17 million copies worldwide, making it the sixth best-selling album of the 21st century. It debuted at number seven on the Billboard 200 with 141,000 copies sold in its first week, peaking at number three in June 2003. The album topped the charts in more than 10 countries. It was certified diamond by the RIAA in November 2022.
