Mourning Sun, released on 28 November 2005, is the fourth studio album by English gothic rock band Fields of the Nephilim.

[1] Vocalist Carl McCoy is the only original band member to be featured on this album and is the band's first studio album since Elizium which was released on 24 September 1990.

McCoy along with John "Capachino" Carter (original Nefilim collaborator) spent eighteen months recording new demos in McCoy's mobile recording studio, dubbed "The Ice Cage" which took them to various places, including Norway.

According to McCoy, Ice Cage sessions generated enough material for a double album, yet it was ultimately decided to narrow the track listing down to one disc.

While McCoy has suggested that additional musicians were recruited for the recording process,[2] the only identified persons involved in the writing and recording process to date are John "Capachino" Carter (a musician who also worked with McCoy on Zoon demos in the beginning of the 1990s) and McCoy's daughters Scarlett and Eden on backing vocals for the title track.
