Hellnation was a hardcore punk band from Covington, Kentucky. The band was active from 1988 to 2010.

The band's sound has been described as thrashcore, powerviolence and grindcore. Hellnation's style was composed of quick guitar riffs, large amounts of distortion, and angry, often profane lyrics. Lyrical subjects included police brutality, consumerism, and the underground punk scene. They completed numerous tours of the United States, Japan, Brazil and Europe.

Originally, Albert Veith was the band's original bassist, however due to the group being unable to find a drummer he switched to the drums. Doug Long joined the group soon after as the bassist before leaving in 1999. Mark Estes was then asked to play bass. After Estes left, Long rejoined. They broke up in January 2010, having released numerous records, most of which were released through guitarist Ken Hansford's label Sound Pollution. Members of the band have since played in groups such as Erectile Dementia, Brody's Militia, and Jacked Up Zeros.

In early May of 2023, Albert Veith, drummer and lead vocalist of Hellnation, died after being hit by a car.
