The Hammerskins (also known as Hammerskin Nation) are a white supremacist group formed in 1988 in Dallas, Texas. Their primary focus is the production and promotion of white power rock music, and many white power bands have been affiliated with the group. The Hammerskins were affiliated with the record label 9% Productions. The Hammerskins host several annual concerts, including Hammerfest, an annual event in both the United States and Europe in honor of deceased Hammerskin Joe Rowan, the lead singer of the band Nordic Thunder.
It was one of the most prominent American white power skinhead groups, along with Volksfront. The Anti-Defamation League describes them as the United States' best-organized neo-Nazi skinhead group, with the Hammerskin Nation website boasting six chapters in the United States and chapters existing in Canada, France, Italy, Germany, Hungary, Portugal, Spain, Sweden, Switzerland, New Zealand and Australia. The Hammerskins also have supporter chapters, known as Crew 38, in most of these countries, for those who do not seek membership but wish to show their appreciation.
