Jules Greenbaum (5 January 1867 – 1 November 1924) was a German pioneering film producer.
He founded the production companies Deutsche Bioscope, Deutsche Vitascope and Greenbaum-Film and was a dominant figure in German cinema in the years before the First World War.
He is also known for his early experiments with sound films around twenty years before the success of The Jazz Singer made them a more established feature of cinema.
