Roland Gérard Barthes (/bɑːrt/; French: [ʁɔlɑ̃ baʁt]; 12 November 1915 – 26 March 1980) was a French literary theorist, essayist, philosopher, critic, and semiotician. Barthes's ideas explored a diverse range of fields and he influenced the development of many schools of theory, including structuralism, semiotics, social theory, design theory, anthropology, and post-structuralism. He was particularly known for developing and extending the field of semiotics through the analysis of a variety of sign systems, mainly derived from Western popular culture.

During his academic career he was primarily associated with the École des Hautes Études en Sciences Sociales (EHESS) and the Collège de France.
