Alkohol (English: Alcohol) is a 1919 German silent drama film directed by Ewald André Dupont and Alfred Lind and starring Wilhelm Diegelmann, Ernst Rückert, and Georg H. Schnell. The film was begun by Lind but finished by Dupont. It was his first major melodrama, and represented a breakthrough in his career. The film's theme and setting foreshadow much of his later work. It was one in a series of "Enlightenment films" examining social issues, which were produced around the time. It premiered at the Marmorhaus in Berlin.
