Bertrand Lavier (b. 1949, Châtillon-sur-Seine, France) is a French artist based in Paris and Burgundy. As a seminal figure in the movement towards appropriation art in the 1980s and 1990s, Bertrand Lavier is perhaps best known for his readymades, created by covering everyday industrial objects such as refrigerators, tables, pianos, and furniture with an impasto layer of paint. He appropriates ubiquitous objects and images in order to reposition them as elements in a strategic critique of consumerism, deeply entrenched visual habits, and art institutions. Fiercely critical of the fetishization of the art object, Lavier considers his work only fully realized as an exhibition—as a constellation of works that generate meaning exclusively through their interrelationships.

His works can be found in major public collections, including those of the Centre Pompidou in Paris, MOCA Grand Avenue in Los Angeles, National Museum of Modern Art Tokyo in Tokyo, and Stedelijk Museum in Amsterdam.
