"Ieya" was the fourth UK single from the post-punk band Toyah, fronted by Toyah Willcox, and was released in 1980. It was later remixed and re-issued in 1982.

This track became an ever-present mainstay of Toyah's live sets, and to this day it is rare for Toyah to play a full set and not perform "Ieya". Its B-side, "Helium Song", was an extended version of the track "Spaced Walking", which, along with "Ieya", featured on the band's first full-length release, The Blue Meaning. Both tracks also featured on the 2005 compilation album The Safari Singles Collection Part 1: 1979-1981.

The single was released in several formats, including three different 7-inch vinyl releases, and for the first time, a 12-inch single.

"Ieya" started off as a jam, on stage. Some months before its release the band played in Bath. The show, according to Toyah, had gone phenomenally well, but the band had trouble with the National Front. Toyah explained:

A lot of my band were Jewish, and we all found it particularly offensive that the NF would recruit at concerts - they'd go around the audience intimidating the youngest, the smallest, the scrawniest boys into joining the NF By the end of this concert in Bath, the NF were chanting 'Sieg heil' at the back. Charlie Francis, our bass-player, found this intolerable, and Joel kept taking his guitar off to go and beat them up, which we all had to stop him from doing. Instead we just shouted back 'Nazi scum' and got the audience to chant 'Nazi scum'. For the fourth encore, all we could think of doing was something that had started as a jam in the sound-check that day, which was 'IEYA'. It was a sequence of chords that grew, so every verse had more chords added to it, and it had a fantastically simple chorus, a chant, 'IEYA'. 'IEYA, I am solar, IEYA I'm the beast.'

"At the end of the concert the NF were so incensed that the police were called and had to get us out via the Gents window at the back and into a police van, because the NF were outside, kicking in cars, waiting for us at the stage door to kick our heads in. A full-blown riot was in progress", Toyah remembered.

"IEYA", according to the singer, "is about mankind believing in ourselves so much that we believe we are immortal and can become our own gods, therefore challenging God as the Devil, in the form of the Devil; man being the beast".

Necronomicon reference ("Zion, Zuberon, Necronomicon") had to do with a paranormal experience of her own. In a 1980 interview Toyah related how nightmare images which were regularly visiting her when she was five all came back to her later in the paintings of H. R. Giger:
