The Great Martian War 1913–1917 is a 2013 Canadian/UK made-for-television science fiction docudrama film, produced by Michael Kot, Steve Maher, and Mike Slee, and also directed by Slee. It unfolds in the style of an episode from the History TV Channel.

The film as presented is an alternate history of World War I: the European Allies, and eventually America, fight Martian invaders instead of Germany and the Central Powers. Europe is on tenterhooks in the second decade of the 20th century. Everyone is expecting war between the European powers. Many references to real events in World War I are woven into the film's fictional narrative, including parallels to the conflict, such as trench warfare and the Christmas truce, and America's late entry into the war. The film also utilizes a surprising twist on the "Spanish" flu pandemic that killed more people than the conflict itself, which becomes the key development in ending the alien invasion.

The film is based on the 1897 science fiction novel The War of the Worlds, by English author H. G. Wells, and includes both new and digitally altered film footage shot from World War I to establish the scope of the interplanetary conflict.
