The discography of heavy metal band Mastodon consists of six studio albums, two live albums, two compilation albums, one video album, four extended plays, twenty-two singles and thirteen music videos.
The band was formed in 1999 by guitarists Brent Hinds and Bill Kelliher, bassist and vocalist Troy Sanders, and drummer Brann Dailor, in Atlanta, Georgia. Mastodon released their debut extended play, Lifesblood, in 2001, followed by the band's first studio album in 2002, Remission. Both recordings were issued through Relapse Records. After a tour promoting the album Remission, Mastodon released their second studio album, Leviathan, in August 2004. In February 2006, Mastodon released two records — first, a compilation of early recordings, titled Call of the Mastodon, and shortly after, the video album, The Workhorse Chronicles. This same year marked the band's debut on a major label. They released Blood Mountain through Reprise Records, peaking at number 32 on the Billboard 200 chart. Mastodon then released Crack the Skye in 2009, The Hunter in 2011, and Once More 'Round the Sun in 2014, which entered the Billboard 200 at number 11, number 10, and number 6 respectively.
