Anthony Cave Brown (March 21, 1929 – July 14, 2006) was an English-American journalist, espionage non-fiction writer, and historian.

Brown’s first major work to attract widespread attention was Bodyguard of Lies (1975), which examined the strategical elements of World War II, including codebreaking and its effect on the war’s outcome. He followed up on this theme with a book, The Last Hero: Wild Bill Donovan, about William J. Donovan, the director of the American Office of Strategic Services during World War II; the Office of Strategic Services later evolved into the Central Intelligence Agency. Another espionage-related effort was a 1987 biography of Sir Stewart Menzies, who served as head of British MI6 (Secret Intelligence Service) during World War II. The book was titled C: The Secret Life of Sir Stewart Graham Menzies, Spymaster to Winston Churchill. His book Treason in the Blood: H. St. John Philby, Kim Philby, and the Spy Case of the Century, published in 1994, examined the interconnected lives of the famous British spies Kim Philby and Harry St. John Philby, son and father. His final 1999 book Oil, God and Gold: The Story of Aramco and the Saudi Kings, examined the Aramco company in Saudi Arabia.
