Iron Man: Original Motion Picture Soundtrack is the soundtrack album to the 2008 film Iron Man, featuring music composed by Ramin Djawadi. The soundtrack was produced in collaboration with Hans Zimmer and Remote Control Productions, and was released on April 29, 2008, by Lions Gate Records.

Djawadi joined the film after John Debney, who previously collaborated with director Jon Favreau, was unavailable. The score focuses heavily on electric guitar, as requested by Favreau, and was recorded with a rock band as well a traditional orchestra. The soundtrack also includes the classic 1966 Iron Man theme song, and a big band-style arrangement of it by John O'Brien and Rick Boston, who also frequently collaborate with Favreau.

The soundtrack was negatively received by critics, especially the score's use of electric guitar and Remote Control influences. However, the inclusion of the classic theme, in its original and modern cover forms, was received positively, and the soundtrack was ultimately nominated at the 51st Grammy Awards.

After Iron Man director Jon Favreau's previous collaborator John Debney was unavailable to score the film,Iron Man fan Ramin Djawadi sought out the role. Filming on Iron Man had already been completed by the time Djawadi joined the production, and rather than wait until he could see the completed film, as he usually would, Djawadi began "playing with ideas" as soon as he saw the first trailer. Due to time constraints and the final cut of the film changing until "the last possible minute", Djawadi had help with arrangements and additional cues from Hans Zimmer and Remote Control Productions.
