Once More 'Round the Sun is the sixth studio album from American heavy metal band Mastodon. The album was released on June 24, 2014, via Reprise Records. On April 17, 2014, Mastodon released the album's first single, titled "High Road". On June 16, 2014 the album was made available for streaming on iTunes. The album sold around 34,000 copies in the United States in its first week of release to land at position No. 6 on The Billboard 200 chart, making it the band's second consecutive top 10 debut after their previous album, The Hunter, peaking at No.10 after opening with 39,000 copies in 2011.

In late 2012, Mastodon guitarist Brent Hinds mentioned in an interview that he had begun writing material for the band's next release. The band continued writing and demoing their sixth studio album throughout 2013, while touring for their 2011 release The Hunter. The band began recording in late 2013 at Rock Falcon Studios in Franklin, Tennessee, with producer Nick Raskulinecz.

Troy Sanders has stated in an interview that the album is a continuation, where the band left off with their previous album (The Hunter).

Bill Kelliher stated also about the album's musical style: "We're always trying to surprise ourselves and write something that's new and fresh. It's definitely got the elements of The Hunter in there, but also [of] Remission and some heavier stuff. There's a lot of different influences, from Alice in Chains to Deftones. There's a lot of rock going on."

Brann Dailor stated following about the album: "It's gonna be massive and insane, lots of epic greatness. There will be lots of huge riffs and new directions. It's real weird, real math-y, real straightforward. It's up, down and all around."
