Blackfield IV is the fourth studio album by Blackfield, the musical collaboration by Aviv Geffen and Steven Wilson. Similar to their third album, Welcome to My DNA, Geffen has taken over more active duties on the album while Wilson focuses on his solo career. The album was released on 26 August 2013.

Over the course of 2010 and early 2011, the two creative directors of Blackfield were split over two musical projects; Steven Wilson wrote and recorded his second solo studio album, Grace for Drowning, and as a result, Aviv Geffen would take more creative control over Blackfield's third studio album, Welcome to My DNA. After both albums' release and promotion, in December 2011, Wilson stated that his various music projects, Blackfield included, would be put on hold, while he focused further on his solo career. Contrary to this announcement, less than a month later in January 2012, Geffen announced his intentions to release a fourth Blackfield album by as soon as May 2012. This prompted Wilson to announce that his role would continue to lessen, with Wilson acting only as a contributor and mixer. Wilson said of the band's future:

...just to clarify news elsewhere of a new Blackfield album coming this year – please note that this time my involvement will be as a contributor rather than a member. I will still be mixing the album, and maybe sing on a couple of Aviv’s songs (there will be other guest singers I understand), but with my complete blessing Blackfield is now under his sole curatorship, a process which really began with Welcome to My DNA"

Wilson later admitted that it was his own idea for Geffen to take over the project, because Wilson wanted to concentrate on his solo career in 2012 and 2013, while Geffen wanted to do another Blackfield album right away in 2012, and Wilson felt guilty about holding him back.

Work on the album started shortly after Geffen's initial announcement. On 29 and 30 January, both Geffen and Wilson began work on vocal and guitar parts in the studio. The two were accompanied by one of the guest vocalists that Wilson had alluded to before, which was revealed to be Vincent Cavanagh of the band Anathema, who recorded vocals for a track, "XRay".
