Orchestral Manoeuvres in the Dark (often abbreviated to OMD) is a synth pop group whose founding members are originally from The Wirral Peninsula, United Kingdom. OMD record for Virgin Records (originally for Virgin's DinDisc subsidiary).

The group was founded in 1978 by Andy McCluskey and Paul Humphreys, after they had been involved in several bands, including The Id. Later drummer Malcolm Holmes and saxophonist Martin Cooper joined. McCluskey and Humphreys formed the core of the outfit until 1989, when the group split. McCluskey then retained the name and continued to record and tour as OMD with a new line-up. Humphreys, Holmes, and Cooper formed The Listening Pool.

In late December 2005, OMD's official website announced a 2006 reformation, for both live performances and a new album, with rehearsals beginning in summer 2006. The planned line up will feature the original 1980's members. The Architecture & Morality tour for late 2006 was postponed until the beginning of 2007.

The tour finally took place in the spring of 2007 featuring Architecture & Morality played in its entirety plus a 'greatest hits' set, although each concert famously ended with stirring rendition of B side/album track and fan favourite 'The Romance of the Telescope'.

Plans are now ahead for the release of a documentary DVD, a live DVD of the 2007 tour (release postponed until 2008) and possibly a new studio album in 2008.
