Mudhoney is an American alternative rock band. Formed in Seattle, Washington in 1988 following the demise of Green River, Mudhoney's members are singer 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.

Mudhoney's early releases on the Sub Pop label, particularly their debut single "Touch Me I'm Sick" and the Superfuzz Bigmuff EP, were massively influential on the Seattle music scene. More than almost any other release of the era they inspired 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 9 studio albums, it has inspired countless grunge and alternative rock musicians.
