Hunter Stockton Thompson (July 18, 1937 – February 20, 2005) was an American journalist and author who wrote The Rum Diary (1998), Fear and Loathing in Las Vegas (1971), Fear and Loathing on the Campaign Trail '72 (1973), The Curse of Lono (1983), and Hell's Angels: The Strange and Terrible Saga of the Outlaw Motorcycle Gangs (1966).

He is credited as the creator of Gonzo journalism, a style of reporting where reporters involve themselves in the action to such a degree that they become central figures of their stories. He is known also for his lifelong use of alcohol, LSD, mescaline, and cocaine (among other substances); his love of firearms; his inveterate hatred of Richard Nixon; and his iconoclastic contempt for authoritarianism. While suffering a bout of health problems, he committed suicide in 2005 at the age of 67.

Thompson was born in Louisville, Kentucky, the first of three sons, to Jack Robert Thompson (September 4, 1893, Horse Cave, Kentucky – July 3, 1952, Louisville), a public insurance adjuster and World War I veteran, and Virginia Ray Davison (1908, Springfield, Kentucky – March 20, 1998, Louisville), a librarian. His parents were introduced to each other by a friend from Jack's fraternity at the University of Kentucky in September 1934, and were married on November 2, 1935.
