Leeland is a Christian rock band from Baytown, Texas. The band was formed in 2004, although lead singer Leeland Mooring had been writing songs beforehand. Leeland consists of Leeland Mooring (lead vocals, guitar), and Casey Moore (guitar, background vocals). The band's original line-up included Jeremiah Wood (guitar), who left the band in late 2006 and was replaced by guitarist Matt Campbell in early 2007, Jack Mooring (piano), Mike Smith (drums) and Jake Holtz (bass).

Leeland has released five studio albums, the latest in July 2016. The band received a Grammy Award nomination and two Dove Award nominations for their debut album Sound of Melodies (2006). The band's third album, Love Is on the Move, was released on August 25, 2009.

Leeland's fourth studio album, The Great Awakening, was released on September 20, 2011, and received a nomination to the 54th Grammy Awards for Best Contemporary Christian Music Album.

After a five-year hiatus, Leeland released their fifth studio album in July 2016, Invisible, via the Bethel Music label.

Lead singer Leeland Mooring wrote his first song, "Shine," at the age of 11. After giving a successful performance of the song at a church in Illinois, the Mooring family began touring the United States. When he was 14, Mooring entered into Embassy Music's Ultimate Talent Search contest in Nashville, Tennessee, becoming a finalist in the songwriting and artist divisions. Although he did not win the competition, one of the contest's judges, Kent Coley, took interest in the young teen. A year later, Eddie DeGarmo, president of EMI CMG Publishing, also expressed interest in Mooring, and the two signed a songwriting contract on EMI/Capitol Music Group. Less than a year later, Leeland Mooring, his older brother Jack Mooring, their cousin Jake Holtz, and friends Jeremiah Wood and Mike Smith, whom the Moorings had known for several years, officially signed as a band onto Essential Records, a subsidiary of Sony BMG's Provident Label Group. The five members began practicing at night after youth group in their church's building, which doubled as a funeral home. Leeland Mooring's first name was used as the band's name because the members said that "it sounded cool".

Leeland began recording for their debut release, Sound of Melodies, in 2005, with Matt Bronleewe, Marc Byrd, and Steve Hindalong producing the album. It was released in the United States on August 15, 2006. At the 49th Grammy Awards on December 7, 2006, the album was nominated for Best Pop/Contemporary Gospel Album. In 2007 the band received five GMA Dove Award nominations, including "New Artist of the Year" and two nominations for their debut album Sound of Melodies. The album was also released in Japan on March 21, 2007, with the title song, "Sound of Melodies," peaking at No. 6 on the general Japan radio chart.

The band has worked closely with Christian music legend Michael W. Smith, who remarked, "Leeland is the best thing I have heard in a long, long time". Leeland Mooring co-wrote six songs on Smith's album Stand, and wrote one song by himself. Jack Mooring married Smith's daughter Whitney Smith-Mooring on June 1, 2007.

After four years as a member of Leeland, Jeremiah Wood left the band in October 2006 to pursue other endeavors. Austin Tirado was hired as a temporary guitar player until February 2007. In February, Matt Campbell was hired as a temporary guitarist; he was added as an official band member after three months.
