Flyleaf is an American rock band that formed in Texas in 2000. They performed around the United States in 2003 until releasing their debut album, Flyleaf, in 2005. The band was named MTV's artist of the week on December 24, 2007.

All five members of the band are of the Christian faith. This faith influences their music, but lead singer Lacey Mosley doesn't necessarily believe that makes Flyleaf a strictly Christian band.
In 2005, the band recorded their first full-length album with Howard Benson. On October 4, 2005, the album was released under the title Flyleaf. Appearances on the album include Dave Navarro of Jane's Addiction and Ryan White of Resident Hero. The most acclaimed singles from their debut album are: "I'm So Sick", "Fully Alive" and "All Around Me". A video has recently been released for the song "Sorrow".

In the summer of 2006, the band played on the Family Values Tour 2006 and in late 2006, Flyleaf toured with Disturbed, Stone Sour and Nonpoint on the Music As A Weapon III Tour. The band issued an exclusive EP, which was sold at the tour called Music As A Weapon EP which features an acoustic version of "Fully Alive", and three previously unreleased tracks: "Much Like Falling", "Justice And Mercy", and "Christmas Song".

In 2007 Flyleaf toured with Three Days Grace and throughout Australia with the Australian Soundwave Festival, and also toured Europe with Stone Sour and Forever Never.
Flyleaf is scheduled to begin recording their new album in fall
