Mudhoney is an American grunge band. Formed in Seattle, Washington, in 1988 following the demise of Green River, Mudhoney's members are vocalist and rhythm guitarist Mark Arm, lead guitarist Steve Turner, bassist Guy Maddison, and drummer Dan Peters. Original bassist Matt Lukin left the band in 1999 but briefly returned in December 2000 to complete touring obligations.

Mudhoney's early releases on Sub Pop, particularly their debut single "Touch Me I'm Sick" and the Superfuzz Bigmuff EP, were massively influential on the Seattle music scene, helping more than almost any other releases of the era to inspire the dirty, high-distortion sound that would become grunge. Later on, Mudhoney also mixed heavy blues rock and punk rock into their sound at various stages. Although the band has found little commercial success during its long career, which has yielded 10 studio albums, it has inspired countless grunge and alternative rock musicians.
