Gérard de Villiers (French: [ʒeʁaʁ də vilje]; 8 December 1929 – 31 October 2013) was a French writer, journalist and publisher whose SAS series of spy novels have been major bestsellers. According to the New York Times, "His works have been translated and are especially popular in Germany, Russia, Turkey, and Japan. The SAS series has sold a reported 120 million copies worldwide, which would make it one of the top-selling series in history, on a par with Ian Fleming's James Bond books. SAS may be the longest-running fiction series ever written by a single author."
