Károly Halász (Károly Hopp-Halász; 28 January 1946 – 27 November 2016) was a Hungarian multimedia artist and co-founder of the Hungarian neo-avant-garde artist group Pécs Workshop (Pécsi Műhely). His multi-faceted œuvre can be seen as an extension of a constructivist language – which remained central throughout his career – to a wide range of media from video, performance, and installation to painting, sculpture, and graphics, as well as various thematic focuses from the deconstruction of mass media to institutional critique.
