Simulacra and Simulation is a 1981 philosophical treatise by the philosopher and cultural theorist Jean Baudrillard, in which he seeks to examine the relationships between reality, symbols, and society, in particular the significations and symbolism of culture and media involved in constructing an understanding of shared existence.

Jean Baudrillard was a French sociologist, philosopher and poet, with interest in cultural studies. He is best known for his analyses of media, contemporary culture, and technological communication, as well as his formulation of concepts such as hyperreality. Baudrillard wrote about diverse subjects, including consumerism, critique of economy, social history, aesthetics, Western foreign policy, and popular culture. Among his most well-known works are Seduction (1978), Simulacra and Simulation (1981), America (1986), and The Gulf War Did Not Take Place (1991). His work is frequently associated with postmodernism and specifically post-structuralism. Nevertheless, Baudrillard had also opposed post-structuralism, and had distanced himself from postmodernism.
