Walter Reimann (2 June 1887 – 8 November 1936) was a German painter and art director. He was an Expressionist and member of the group of artists associated with Zurich magazine, Der Sturm. He worked on the production design of a number of films during his career, the most important of which was The Cabinet of Dr. Caligari. Reimann continued to work as an art director in Germany until his death in 1936, but none of his subsequent designs had the impact of Caligari. In 2017, the Art Directors Guild honored Reimann's work and legacy with a tribute at Grauman's Egyptian Theatre in Hollywood.
