Simulacra and Simulation is a postmodern novel written by Jean Baudrillard. Baudrillard's original work was written in French; the title was Simulacra et Simulation.

Containing seventeen chapters, Simulacra and Simulation is most known for its discussion of images, signs, and how they relate to the present day. Baudrillard claims that our society has replaced all reality and meaning into symbols and signs, and that in fact all that we know is real is actually a simulation of reality. The simulcra that Baudrillard refers to are signs of culture and media that create the reality that we perceive.

A specific analogy that Baudrillard uses is a 'Borges fable'. In it, the legend is that a great Empire created a map that was so detailed it was as large as the Empire itself. The actual map grew and decayed as the Empire itself was conquered or lost territory. When the Empire crumbled, all that was left was the map. In Baudrillard's rendition, it is the map that we are living in, the simulation of reality, and it is reality that is crumbling away from disuse.

The Matrix, a popular sci-fi film, makes many connections to Simulcra and Simulation. In fact, the principal character of The Matrix, Neo, can be seen with a copy of Simulacra and Simulation, although the book in the Matrix was designed with the chapter "On Nihilism" to be in the middle, and not at the end where it is located in the real book. Morpheus also refers to the real world outside of the Matrix as the "desert of the real", a direct reference to Baudrillard's work. In the original script, Morpheus referenced Baudrillard's book specifically.
