"Nancy Boy" is a song by British alternative rock band Placebo, released on 20 January 1997, as the fourth single from their debut self-titled album, released on Hut Records. As with their first single "Come Home", the single edit is a re-recorded version, noticeably different from the album version. "Nancy Boy" contains themes of drugs, sex, gender confusion and bisexuality. "Nancy Boy" became their breakthrough single, peaking at number four in the UK Singles Chart a month after the single's release. While Placebo originally charted at number forty upon its release, after the release of "Nancy Boy" the album re-entered the UK Albums Chart at number five in February, staying on chart for thirteen weeks.
