Opus Nocturne is the third studio album by Swedish black metal band Marduk.

It was recorded and mixed at Hellspawn Studios in September 1994 and released on 4 December 1994 by Osmose Productions.

In 2004 the album was remastered by the band's former member Devo Andersson and re-released on 27 June 2006 by Regain Records as a digipak that included bonus rehearsal tracks.

Opus Nocturne is the last Marduk album to feature Joakim Göthberg on vocals and Dan Swanö as mixer.

[citation needed] "Materialized in Stone" was originally the title for the track "From the Dark Past" that appears on Mayhem's De Mysteriis Dom Sathanas.
