Terrifyer is the third studio album by American grindcore band Pig Destroyer.

The album includes a second disc recorded in DVD-Audio and mixed with 5.1 surround sound.

The Japanese release of Terrifyer includes four bonus tracks and "Natasha" as a second CD instead of a DVD.

Some copies of Terrifyer were released with a slip of paper on the cover to hide the artwork.

In 2017, Rolling Stone ranked Terrifyer as 88th on their list of "The 100 Greatest Metal Albums of All Time".
