Facing the Flag or For the Flag is a patriotic novel by Jules Verne. Like The Begum's Millions which Verne published in 1879, it has the theme of France and the entire world threatened by a super-weapon (what would now be called a weapon of mass destruction) with the threat finally overcome through the force of French patriotism.

It can be considered one of the first books dealing with problems which was to become paramount half a century after its publication: brilliant scientists discovering new weapons of great destructive power, whose full utilisation might literally destroy the world; the competition between various powers to obtain control of such weapons; and also the efforts of ruthless non-state groups to have it.

Jules Gabriel Verne was a French author who pioneered the genre of science-fiction. He is best known for his novels Journey to the Center of the Earth (1864), Twenty Thousand Leagues Under the Sea (1870), and Around the World in Eighty Days (1873).

Verne wrote about space, air, and underwater travel before navigable aircraft and practical submarines were invented, and before any means of space travel had been devised. He is the second most translated author of all time, behind Agatha Christie. His prominent novels have been made into films. Verne, along with H. G. Wells, is often referred to as the "Father of Science Fiction".
