"Nancy Boy" is a song by British alternative rock band Placebo, released on 20 January 1997, as the fourth single from their debut album 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" differs from previous songs' themes about 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 singles 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.
