Go Go Smear the Poison Ivy is an album by the Icelandic group múm. It was released on the Fat Cat label on 24 September 2007.
The album marks a shift from the group's original style as it uses more live instruments than electronics, and there is a different vocal style, including male vocals. Almost two years prior to the release of this album, former lead singer of múm, Kristín Anna Valtýsdóttir, departed from the band. According to reviews this is believed to be one reason for the break of style compared to earlier releases.
The seventh song is listed as "Rhubarbidoo" in the album liner notes, while it is named "Rhuubarbidoo" on the "Marmalade Fires" single.
