"Heroine" is a song by British pop act Shakespears Sister, released in 1988 as a single from their debut album Sacred Heart. "Heroine" was released in most territories as a Double A-side with "Break My Heart (You Really)", which according to Siobhan Fahey was to "give a more rounded picture of what I'm about". In North American territories however, both songs were released as separate A-side singles.
