"Sister Marie Says" is the 32nd UK single from English electronic band Orchestral Manoeuvres in the Dark (OMD), released on 15 November 2010.

The subject of the song is self-styled nun, prophet and astronomer 'Sister Marie Gabriel' (a.k.a.

; b. Poland, 1941) who became notorious for producing apocalyptic warnings of imminent world doom.

This later culminated in 1994 with her publishing (from her London flat) alarming full-page advertisements in several British national daily newspapers, incorrectly predicting "God's final warning", a supposed massive fireball directed across space at planet Earth from Jupiter, resulting from the (already predicted) impact of comet Shoemaker-Levy 9.

On 26 October 2010, the limited edition 7" vinyl single was released for pre-order on the band's website.
