The Blue Hussar (French: Le hussard bleu) is a 1950 novel by the French writer Roger Nimier. Set in Germany in 1945–1946, it tells the story of ten French hussars who operate in the French occupation army right after World War II. The perspective shifts between several different people. At the centre are the ambivalent François Sanders and his companion François Saint-Anne—the title character—who unknowingly share the same German mistress.
