"Break My Heart (You Really)", also known as "Break My Heart", is a song by British pop act Shakespears Sister, released in 1988 as the lead single from their debut album Sacred Heart. "Break My Heart (You Really)" was released in most territories as a Double A-side with "Heroine", 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.
