"Women in Uniform" is a 1978 song originally recorded by the Australian band Skyhooks; it was written by the band's bass player, Greg Macainsh. It appeared on their fourth album, Guilty Until Proven Insane, and was a top 10 single in Australia.

The single was released in Australia both in a 7" and 12" format with the non-LP B-sides "Don't Take Yur Lurex To The Laundromat" and "Do The Hook". The international version of the single contained "BBBBBBBBBBBBBBoogie" from the Guilty Until Proven Insane album.

Iron Maiden's cover of the song was the band's third single and their last recorded work to feature guitarist Dennis Stratton. It was released on 27 October 1980 in order to promote the second British leg of their Iron Maiden Tour. The song was also included on the Australian edition of their second album Killers, as it was originally a number eight hit in Australia for Skyhooks in 1978. In 1990, the 12" version was reissued on CD and 12" vinyl as part of The First Ten Years box set, in which it was combined with their following single, "Twilight Zone".

The idea to cover the song was suggested by the band's publishing company, Zomba, who set them up with studio time at Battery Studios with AC/DC producer Tony Platt. Although sceptical at first about recording a song that was so different from the band's style, bassist Steve Harris conceded when Platt was hired, surmising that "as he worked with AC/DC and that, I thought, 'Oh, you know, fine. He's not gonna pull us in any commercial direction.'" After trying to create their own "heavy" version of the song, to Harris' dismay he found out that Platt, with help from Stratton, had been tampering with the song's mix as he had been briefed by Zomba to "Try and get a hit single." As a result, Platt was dismissed and Harris remixed the track himself.
