King Gizzard & the Lizard Wizard (KGLW) are an Australian rock band formed in 2010 in Melbourne, Victoria. The band's current lineup 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.

The band's early releases blended surf music and garage rock and were released on their label, Flightless. They released several psychedelic and progressive rock albums in the early 2010s, and incorporated a broader range of musical styles later in the decade, such as jazz fusion on Quarters! and the folk-inspired Paper Mâché Dream Balloon. In 2016, they generated more mainstream attention with Nonagon Infinity, which 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, and also marked the beginning of a trilogy of microtonal albums with Flying Microtonal Banana. Subsequent releases integrated heavy metal, synth-pop and progressive rock, and feature lyrics that address environmental themes and a connected fictional universe termed the "Gizzverse" by fans. Eric Moore, the second drummer and manager, left in 2020. Since 2019, the band has produced several albums per year, including releasing five in 2022 with three of the releases in that October. Their 26th and most recent album, Flight b741, was released in 2024.
