Walter Flex (6 July 1887 – 16 October 1917) was a German author of "The Wanderer between the Two Worlds: An Experience of War" ("Der Wanderer zwischen beiden Welten") of 1916, a war novel dealing with themes of humanity, friendship, and suffering during World War I. Due to his idealism about Prussian virtues and the Great War, as well as the posthumous popularity of his writings, Walter Flex is sometimes compared to Allied war poets Rupert Brooke and Alan Seeger.
