Discovery is the ninth studio album by English multi-instrumentalist and songwriter Mike Oldfield, released on 25 June 1984 on Virgin Records.

After his 1983 tour, Oldfield relocated to Villars-sur-Ollon, Switzerland for tax purposes and started work on a new album.

Discovery was re-released in a deluxe edition format on 29 January 2016,[7] as per all previous albums which were originally released on the Virgin label.

The reissue comprises 2 CDs (Discovery and the 1984 Suite) and a DVD featuring 5.1 surround sound mixes.

It also includes two previously unreleased tracks: "The Royal Mile", a slight reworking of the 1984 track "Afghan", and "Zombies (Halloween Special)", a reworking of the song "Poison Arrows" with the original vocals replaced by a "Macintalk" voice named Fred and the lines "Somebody's out to get you" replaced with "Zombies are out to get you".
