Dead Congregation are a Greek death metal band from Athens formed in 2004.

The band was founded by lead guitarist and vocalist Anastasis Valtsanis after the split-up of Nuclear Winter. Nuclear Winter started off as a crust punk band. Later, they began incorporating some influences from the early Swedish death metal scene. Their debut release was a self-financed EP, which already presents a blending of those styles. After a long hiatus, the band released in 2000 a split with Incriminated from Finland. Before the break-up of Nuclear Winter, Valtsanis recorded one last demo with the band. After one of bandmates quit the group, Valtsanis recorded the Abomination Virginborn demo as band's chief songwriter.
