The Turner Diaries is a 1978 white supremacist propaganda novel by American neo-Nazi William Luther Pierce under the pseudonym Andrew Macdonald. It is one of the most prominent works of fiction in Western white supremacy and has been called the "bible of the racist right" by the Federal Bureau of Investigation.

The Turner Diaries portrays violent fantasies of murdering Jewish people, people of colour, journalists, and white women in relationships with non-white men, as told by a white supremacist protagonist. It has directly inspired white supremacist terror attacks including the murders of Alan Bergs and James Byrd Jr, and was favoured by Timothy Mcveigh, a culprit of the Oklahoma City bombing that killed 168 people.

The novel's name, cover art, and its "Day of the Rope" fantasy are commonly referenced in a modern white supremacist culture, including in the form of internet memes.
