"Shut Your Mouth" is a 2001 alternative rock song by Garbage, written and recorded for their third studio album Beautiful Garbage. "Shut Your Mouth" was the album opener; it was also released as its fourth and final single.

Beautiful Garbage is the third studio album by American rock band Garbage. It was released on October 1, 2001, by Mushroom Records worldwide, with the North American release by Interscope Records the following day. Marking a departure from the sound the band had established on their first two releases, the album was written and recorded over the course of a year, when lead singer Shirley Manson chronicled their efforts weekly online, becoming one of the first high-profile musicians to keep an Internet blog. The album expanded on the band's musical variety, with stronger melodies, more direct lyrics, and sounds mixing rock with electronica, new wave, hip hop, and girl groups.
