King Gizzard & the Lizard Wizard are an Australian rock band formed in 2010 in Melbourne, Victoria. The band's current line-up consists of Stu Mackenzie, Ambrose Kenny-Smith, Cook Craig, Joey Walker, Lucas Harwood and Michael Cavanagh. They are known for exploring multiple genres, staging energetic live shows and building a prolific discography, having released 22 studio albums, 14 live albums, three compilations and three EPs.

Their second EP, Willoughby's Beach, and debut album, 12 Bar Bruise, primarily blended surf music and garage rock, and were released on Flightless, the band's own label. Their second album, a "psychedelic spaghetti western" titled Eyes Like the Sky, features spoken-word narration by Broderick Smith. Float Along – Fill Your Lungs, released later in the year, and the 2014 albums Oddments and I'm in Your Mind Fuzz, saw the band expand on their psychedelic sound. In 2015, they drew on elements of jazz fusion and progressive rock with Quarters!, and also released the folk-inspired Paper Mâché Dream Balloon, recorded almost entirely using acoustic instruments. Nonagon Infinity features nine interconnected tracks that form an infinite loop, and won the ARIA Award for Best Hard Rock or Heavy Metal Album.In 2017, the band fulfilled a promise to release five studio albums within the year: Flying Microtonal Banana, an experiment in microtonality, in February; the three-chapter "sci-fi heavy metal epic" Murder of the Universe in June; Sketches of Brunswick East, an improvised jazz collaboration with Mild High Club, in August; Polygondwanaland, which was released into the public domain, in November; and Gumboot Soup in December. The 2019 albums Fishing for Fishies and Infest the Rats' Nest saw the band tackle environmental themes and incorporate boogie rock and thrash metal into their sound, respectively.

In the 2020s, the band released two further microtonal studio albums – K.G. and L.W. – and the synth-based dream pop album Butterfly 3000 (all released independently) as well as several live albums, a concert film and two compilations. Eric Moore (the band's second drummer and manager) left the band in 2020 to focus on running record label Flightless. In 2022, King Gizzard released Made in Timeland, their first double album, Omnium Gatherum, and will release three further albums – Ice, Death, Planets, Lungs, Mushrooms and Lava, Laminated Denim and Changes – in October of the same year.

In a 2019 study conducted by the Institute of Contemporary Music Performance, King Gizzard and the Lizard Wizard was ranked No. 21 in a list of the world's hardest-working musicians. This was earned due to the amount of live shows they played from January 2018 to August 2019 – totalling to 113 live performances both domestically and internationally.
