Nonagon Infinity is the eighth studio album by Australian psychedelic rock band King Gizzard & the Lizard Wizard. It was released on 29 April 2016 on ATO Records.^[1] The album is designed to play as an "infinite loop" where each song segues into the next and the last song segues into the first, so that "the record can be played front-to-back-to-front-to-back and the sound won't break".^[3] The title is a reference to this idea, as there are nine songs on the album that could be played "infinitely".

Considered the band's breakthrough album, Nonagon Infinity earned positive reviews from critics and gave King Gizzard greater international exposure, while becoming their first release to make the top 20 of the Australian albums chart. The album "controversially" won Best Hard Rock/Heavy Metal album at the ARIA Music Awards of 2016, with some accusing the ARIA of miscategorizing Nonagon Infinity.^[4] The album won Best Album at the Music Victoria Awards of 2016.^[5][6]

The band has referenced or expanded upon various aspects of the album on subsequent projects. The opening track, "Robot Stop", briefly features use of microtonal tuning, a technique explored further on the band's follow-up, Flying Microtonal Banana, while themes from Nonagon Infinity were revisited in "The Lord of Lightning vs. Balrog" suite from their 2017 album, Murder of the Universe.

Director Edgar Wright has since cited the album as one of his favorite albums of all time, stating that "you could be forgiven for thinking you were hearing one long extended track, but my God does it rock."^[20]

Matthew Coakley of The Triangle said the album was musically a gritty, heavy, lo-fi garage rock aesthetic and created a 'never-ending loop' of an album where all the songs flow directly into one another.^[21]

Jamie McNamara of BeatRoute magazine called it "a rollicking, garage-rock epic".^[22]
