John Dann MacDonald (July 24, 1916 – December 28, 1986) was an American writer of novels and short stories, known for his thrillers.
MacDonald was a prolific author of crime and suspense novels, many of them set in his adopted home of Florida. His best-known works include the popular and critically acclaimed Travis McGee series, and his novel The Executioners, which was adapted into the film Cape Fear. In 1972, MacDonald was named a grandmaster of the Mystery Writers of America, and he won a 1980 U.S. National Book Award in the one-year category Mystery. Stephen King praised MacDonald as "the great entertainer of our age, and a mesmerizing storyteller." Kingsley Amis said, MacDonald "is by any standards a better writer than Saul Bellow, only MacDonald writes thrillers and Bellow is a human-heart chap, so guess who wears the top-grade laurels?"
