The War is a series of 50 drypoint and aquatint etchings by German artist Otto Dix, catalogued by Florian Karsch as K.70 to K.119. The prints were published in Berlin in 1924 by Karl Nierendorf, in an edition which included separate high quality folio prints, and a lower-quality version with 24 prints bound together. It is often compared to Francisco Goya's series of 82 engravings The Disasters of War. The British Museum, which holds a complete set of the folio prints, has described the series as "Dix's central achievement as a graphic artist"; the auction house Christie's has described it as "one of the finest and most unflinching depictions of war in western art".

Wilhelm Heinrich Otto Dix was a German painter and printmaker, noted for his ruthless and harshly realistic depictions of German society during the Weimar Republic and the brutality of war. Along with George Grosz and Max Beckmann, he is widely considered one of the most important artists of the Neue Sachlichkeit.
