December 21, 1984 is a live album by Slovenian industrial pioneers Laibach.

The album was recorded on 21 December 1984 at Malči Belič Hall in Ljubljana, Slovenia[1] and on 26 April 1985 at Kulušić in Zagreb, Croatia, both then part of the former Yugoslavia.

[2] It was released in 1997 by The Grey Area, a sublabel of Mute Records.

The part of the album recorded in Ljubljana was taken from a concert dedicated to the deceased former member Tomaž Hostnik.

It was held in secret due to the band being banned from using the name Laibach.
