Sunn O))) (pronunciation: /sʌn/ sun) is an American drone metal band from Seattle, Washington that formed in 1998. The band is primarily known for its synthesis of diverse genres including drone, ambient, noise, and extreme metal, and for its notably loud live performances. Supported by a varying cast of collaborators, the band was formed by two core members: Stephen O'Malley (also of Khanate and Burning Witch) and Greg Anderson (of Goatsnake and Engine Kid).

Sunn O))) is named after the Sunn amplifier brand, the logo of which includes a circle next to the "SUNN" banner with waves heading off to the right. In interviews, Stephen O'Malley stated that the band's moniker was also chosen as a play on the name Earth, a band widely regarded as pioneers of drone metal throughout the 1990s. Before the band members moved to Los Angeles, it briefly used the moniker Mars.

The band's style is characterized by extremely slow tempos, heavily distorted guitars, avoidance of rhythm and melody, and alternate tunings. The guitars are notable for their low register, frequently utilising tunings as low as dropped A. Additionally, the band is known for using resonant feedback to create monolithic soundscapes and eerie atmospheres. Percussion is almost never incorporated, with a lack of any discernible beat. When performing live, the band wears robes, fills the air with fog, and plays at an extremely high volume.
