Robert Neppach (2 March 1890 – 18 August 1939) was an Austrian architect, film producer and art director. Neppach worked from 1919 in the German film industry. He oversaw the art direction of over 80 films during his career, including F.W. Murnau's Desire (1921) and Richard Oswald's Lucrezia Borgia (1922). Neppach was comparatively unusual among set designers during the era in having university training.
