The Turner Diaries is a 1978 novel by William Luther Pierce, a neo-Nazi and the founder and chairman of National Alliance, a white nationalist group, published under the pseudonym Andrew Macdonald. The Turner Diaries depicts a violent, right-wing revolution in the United States that overthrows the federal government, starts a nuclear war, and a race war that leads to the systematic extermination of non-white peoples and the Jews. All groups opposed by the novel's protagonist, Earl Turner—including Jews, non-white people, "liberal actors," and politicians—are murdered en masse.

The Turner Diaries was described as being "explicitly racist and anti-Semitic" by The New York Times and has been labeled the "bible of the racist right" by the FBI. The book was greatly influential in shaping white nationalism and the later development of the white genocide conspiracy theory. It has also inspired numerous hate crimes and acts of terrorism, including the 1984 assassination of Alan Berg, the 1995 Oklahoma City bombing, and the 1999 London nail bombings. It is estimated to have influenced perpetrators in over 200 killings.
