Damaged Goods is an original Doctor Who novel, released by Virgin Publishing in their New Adventures range of Doctor Who books. It is the second and to date last piece of full-length prose fiction to have been published by the television scriptwriter Russell T. Davies, who later became the chief writer and executive producer of the Doctor Who television series when it was revived in 2005. Davies's first professionally-published fiction, a novelisation of his children's television serial Dark Season, had been released by BBC Books in 1991.

Like all Doctor Who spin-off media, the way the plot fits in to the ongoing story of television series is open to interpretation. See inclusion and canonicity in the Whoniverse
