Leviathan II is the eighteenth studio album by Swedish symphonic metal band Therion.

It was released on 28 October 2022 by Nuclear Blast Records.

According to Christofer Johnsson, this second part of the trilogy attempts aimed towards a "more moody and melancholic"[2] sound, that rekindles the "mystic, melancholic aura" of their groundbreaking work Vovin.

[3] As with most Therion albums, all songs are based on various mythologies, as well as other mystical traditions and lore.

Leviathan II was well-received; Allmusic considered that, because of its diversity, it wouldn't appeal to every listener, but it still "does offer plenty for those who enjoy the more classical and prog metal characteristics in the band's sound".
