James J. Martin (September 18, 1916 – April 4, 2004) was an American revisionist historian and author known for espousing Holocaust denial in his works. He is known for his 1964 book, American Liberalism and World Politics, 1931–1941. Fellow Holocaust denier Harry Elmer Barnes called it "unquestionably the most formidable achievement of World War II Revisionism."
Martin was a close associate of historian Harry Elmer Barnes. Martin's own views were libertarian and individualist anarchist. He was also an egoist influenced by Max Stirner and rejected the natural rights views held by some other libertarians. His work was praised by New Left historian William Appleman Williams, libertarian theorist Murray Rothbard, and others.
After a teaching career at Northern Illinois University, San Francisco State College, and Deep Springs College, he took a job teaching at Robert LeFevre's Rampart College, assuming it would be a full-time job. This was not the case as Rampart College was not yet really a college but only a series of workshop/lectures on libertarian political economy. That led to an eventual falling out between Martin and LeFevre when Rampart College went out of business three years after Martin was hired, with Martin charging LeFevre with a breach of his five-year contract.
In 1968, after Rampart College folded and Barnes had died, Martin founded the small Ralph Myles Publisher in Colorado Springs, at first to publish Harry Elmer Barnes: Learned Crusader. Ralph Myles also reprinted Men Against the State, published a new book by Lawrence Dennis, reprinted a history of American anti-militarism by Arthur Ekirch, and brought several World War I revisionist books and a series of classic anarchist writings back into print, most notably No Treason: The Constitution of No Authority by Lysander Spooner and In Quest of Truth and Justice by Harry Elmer Barnes. Martin also was the author of books on anti-war subjects including Revisionist Viewpoints and The Saga of Hog Island, both of them collections of anti-World War II essays, and An American Adventure in Bookburning, a history of censorship in the United States during World War I.
