Sacred Heart is the debut studio album by British pop-rock act Shakespear's Sister, released on 21 August 1989 by FFRR Records.

The album was recorded after Siobhan Fahey decided to leave the girl group Bananarama.

[6] Shakespears Sister was the first musical outing of Siobhan Fahey after leaving the successful girl group Bananarama in 1988.

Fahey began working on Sacred Heart the same year with producer Richard Feldman, who later invited Marcella Detroit to collaborate as a songwriter.

[9] A double A-side of "Break My Heart (You Really)" / "Heroine" was released in October 1988 as the album's lead single which, according to Fahey, was to "give a more rounded picture of what I'm about".

[10] In North American territories however, "Break My Heart (You Really)" was released as a standalone single, followed by "Heroine" in 1989.
