In Norse mythology, Naglfar was a ship made entirely from the nails of the dead. During Ragnarök, Naglfar will be freed from the land by a flood and sail to Vagrond, (also known as Vigrid or Vigrond), the battlefield, by Hymir along with an army of giants. The ship will lead the hordes of evil against the gods in the last war at the end of time, before a new world will arise from the sea.

Naglfar (not to be confused with the German Nagelfar) is a black metal band from Sweden. The group was formed by Jens Rydén and Kristoffer Olivius, originally under the name "Uninterred". The group's style combines traditional black metal with certain melodic death metal elements, sometimes referred to as "Blackened Death Metal".
