Einherjer is a Viking metal band from Haugesund, Norway, founded in 1993. Some of the band's albums are heavily folk influenced, while others have a more traditional black metal sound. Their lyrics retell Norse legends, and each of their albums has its own theme. The band split up in early 2004 after releasing the album Blot in December 2003, but later reformed .
In December 2004, all members of Einherjer's last lineup, including the band's founders Frode Glesnes and Gerhard Storesund, founded the thrash metal band Battered together with bass guitarist Ole Moldesæther.
