Erich Karl Heinrich Kettelhut was a German production designer, art director and set decorator. Kettelhut is considered as one of the most important artists in the history of early German cinema, mainly for his set direction for Die Nibelungen and his design and visual effects for Metropolis .

Despite being best known for his iconic visuals on several of the most important films of German Expressionist cinema, he is also noted for a career spanning into the 1960s and his work on more lighthearted films and musicals.
Kettelhut was born in Berlin in 1893. After leaving school, he received training at a craft school as a theatre artist. In 1909 he first met Otto Hunte, when they were placed in charge of art direction at the Aachens Stadttheater. The two became longtime collaborators during their early cinema careers. From 1910 until 1912 Kettelhut studied at the College of Applied Arts in Berlin. This was followed by time spent as an apprentice in local theatres around Germany including a period as a scene painter at the Metropolitan Opera in Berlin and a role as the head of the design department in Mhlhausen. His role in theatre was interrupted when Kettelhut was called to serve at the Front in 1914.
