Jan Vermeulen, the Miller of Flanders (German: Jan Vermeulen, der Müller aus Flandern) is a 1917 German silent war drama film directed by Georg Jacoby. It was made as a propaganda film by the German film agency BUFA, which generally specialised in making documentaries but also made feature films such as this and Dr. Hart's Diary.
