Guttermouth is an American skate punk band formed in 1988 in Huntington Beach, California, USA and currently recording for Volcom Entertainment. They have released nine full-length studio albums and two live albums and have toured extensively, including performances on the Vans Warped Tour.

They are infamous for their outrageous lyrics and behavior which are deliberately explicit, offensive and intended to shock, though usually in a humorous and sarcastic manner. This behavior has sometimes resulted in high-profile problems for the band, such as being banned from performing in Canada for a year and leaving the 2004 Warped Tour amidst controversy over their political views and attitudes towards other performers.

In 2005 drummer Ty Smith left Guttermouth to focus on his new band Bullets and Octane and was replaced by Ryan Farrell. Bass player Kevin Clark departed the following year and founding member Clint Weinrich returned to the group.

This lineup recorded the band's tenth album Shave the Planet, released in 2006 by Volcom Entertainment. The album found the band once again using their brand of humorous punk rock to poke fun at a number of subjects.

Guttermouth continues to tour and perform in support of the album.
