PetroDragonic Apocalypse; or, Dawn of Eternal Night: An Annihilation of Planet Earth and the Beginning of Merciless Damnation (often shortened to just PetroDragonic Apocalypse) is the 24th studio album by Australian rock band King Gizzard & the Lizard Wizard, released on 16 June 2023.

Recorded based on jam sessions, the album sees the band incorporating a heavy metal style. Lead vocalist Stu Mackenzie stated that the album’s concept is “about humankind, and it’s about planet Earth, but it’s also about witches and dragons, and shit.” Bassist Lucas Harwood has stated that the album is the first of two albums with a “Yin and Yang” concept, describing the two albums as “going to be very different sounding to each other, but we’re going to try to make them complement each other.”
