Ethereal Tomb is the third and final full-length studio album from Florida death metal band, Nocturnus. It was released in 1999 on Season of Mist Records after nearly seven years since the band's last material, the Nocturnus EP was released. Emo Mowery had taken up vocal duties as well as bass, and Rick Bizarro played the drums.
A compilation album of early Nocturnus demos was released in 2004. However, this album remains their final studio outing to date.
