"Omen" is a song by Orbital, released as a single in the UK on 10 September 1990.

Other tracks on the single are the Deeper remix "2 Deep" and "Open Mind".

Early printings of the release had "Omen 7" mix" as track 2, mislabeled "2 Deep" on the tracklist.

"Omen" samples "Song to the Siren" by This Mortal Coil and "(How to Be A) Millionaire" by ABC.

The record sleeve was designed by the usual Orbital collaborator Gavin Fultano (Fultano 90) with photography by Sally Harding and computerised by Chris Smith.
