"United/Zyklon B Zombie" is the debut single by industrial band Throbbing Gristle.

The single's A-side, "United", was called "one of the first electropop singles" by Jon Savage,[4] while the B-side, "Zyklon B Zombie", has been seen as a parody of punk rock music.

[5] "United" featured a minimal drum loop and synthesizer pattern with uncharacteristically positive lyrics, while "Zyklon B Zombie" featured little more than growling, distorted vocals and bass guitar with a frenetic guitar solo.

The original pressing by Industrial Records had its own unique label and logo.

Cosey Fanni Tutti's guitar on "Zyklon B Zombie" was much louder on this repress than the original version.
