The Trap: What Happened to Our Dream of Freedom is a BBC documentary series by English filmmaker Adam Curtis, well known for other documentaries including The Century of the Self and The Power of Nightmares. It began airing in the United Kingdom on BBC Two on 11 March 2007.

The series consists of three one-hour programmes which explore the concept and definition of freedom, specifically, "how a simplistic model of human beings as self-seeking, almost robotic, creatures led to today's idea of freedom."

The series was originally entitled Cold Cold Heart and was scheduled for transmission in Autumn 2006. Although it is not known what caused the delay in transmission, nor the change in title, it is known that the DVD release of Curtis's previous series The Power of Nightmares had been delayed due to problems with copyright clearance, caused by the high volume of archive soundtrack and film used in Curtis's characteristic montage technique.

Another documentary series based on very similar lines—"examining the world economy during the 1990s"—was to have been Curtis's first BBC TV project on moving to the BBC's Current Affairs Unit in 2002, shortly after producing Century of the Self.
