The Acacia Strain is an American band from Springfield, Massachusetts. Even though the band is commonly classified as deathcore, the members of the band deny the label, and feel they are just "heavy". Originally founded in 2001, the band itself has undergone numerous changes in the member line-up. To date they have released five studio albums, as well as two split albums; one with Loyal to the Grave on which they cover the Slayer song "Seasons in the Abyss" and another with This or the Apocalypse, War from a Harlot's Mouth, Fact, and Aggressive Dogs. The band has worked with acclaimed producers Adam Dutkiewicz and Chris "Zeuss" Harris.[citation needed]

The band released their DVD, The Most Known Unknown, on February 16, 2010. The band reached the Billboard Top 200 albums chart in 2008 with Continent and 2010 with Wormwood.
