Shut Your Mouth is the fifth studio album by Australian punk rock band Frenzal Rhomb, released on 20 November 2000.

Originally scheduled to be released on 6 November, it was the first and last Frenzal Rhomb album to be issued in Australia on the Epic label which dropped the band less than six months later.

It was released by Fat Wreck Chords around the world and re-issued by Epitaph/Shock Records in the band's native Australia with the U.S. track listing.

[2] Both Whalley and McDougall noted that the upside of the experience was the large cash advance from their label Sony, who dropped Frenzal Rhomb shortly afterwards without requiring the band to pay this money back.

This version of the album came in a stickered sleeve and with a multimedia component with a 'My City Of Sydney' film clip (not available anywhere else) and an interview with the band members.
