"The Paranoid Style in American Politics" is an essay by American historian Richard Hofstadter, first published in Harper's Magazine in November 1964. It was the title essay in a book by the author the following year. Published soon after Arizona senator Barry Goldwater won the Republican Party presidential nomination over the more moderate Nelson Rockefeller, Hofstadter's article explores the influence of a particular style of conspiracy theory and "movements of suspicious discontent" throughout American history.
