Isis / Pig Destroyer is a split EP by the bands Pig Destroyer and Isis, released in 2000. The EP features the two bands playing cover songs.

Isis (; ; original Egyptian pronunciation more likely "Aset" or "Iset") is a goddess from the polytheistic pantheon of Egypt. She was first worshiped in Ancient Egyptian religion, and later her worship spread throughout the Roman Empire and the greater Greco-Roman world. Isis is still widely worshiped by many pagans today in diverse religious contexts; including a number of distinct pagan religions, the modern Goddess movement, and interfaith organizations such as the Fellowship of Isis.

Islamic State of Iraq and the Levant (ISIL, ), alternatively translated as Islamic State of Iraq and Syria or Islamic State of Iraq and al-Sham (ISIS, ), is a Salafi jihadist militant group that follows an Islamic fundamentalist, Wahhabi doctrine of Sunni Islam. The group is also known as Daesh ( dāʿish, ), which is an acronym derived from its Arabic name .

The Melvins and Isis released a split EP on Hydra Head Records in 2010, with each band contributing two tracks. Isis' "Way Through Woven Branches" had previously only been available as a bonus track on the Japanese edition of their last full-length, Wavering Radiant, whilst "Pliable Foe" was exclusive to this release. Both tracks were recorded during the Wavering Radiant sessions. Meanwhile, the Melvins tracks are reworked from their release The Bride Screamed Murder, described as displaying the "dadaist/trickster tendencies of the band which has frustrated and delighted fans in equal measure since (very nearly) the beginning of their existence". The album was released 13 July 2010 on CD format, with vinyl copies available a week earlier from Vacation Vinyl in Los Angeles.
