"Complex" is a song by British musician Gary Numan.

[2] The recording's backing track uses conventional acoustic drums, acoustic piano, and electric bass guitar, joined by violin (played by Ultravox's Billy Currie), viola and heavily flanged and reverberated analogue monosynth.

[3] Despite the success of the single, which spent two weeks in the UK top 10 during a nine-week chart run,[2] Numan later regretted "Complex" as the choice of a single and that the second single of The Pleasure Principle should have been "Metal".

The song was performed live on the "Pleasure Principle 30th anniversary tour" in 2009, featuring guest appearances by Chris Payne who plays viola on the original recording.
