Michael Anthony Hoffman II (born January 2, 1957) is an American author. He has been described as a conspiracy theorist, Holocaust denier, and anti-semite.

Hoffman was born in Geneva, New York. His father was the chief of physical therapy at Clifton Springs Hospital in the village of Clifton Springs, New York.^{[citation needed]} His mother was Italian-American. According to biographical information on the back cover of his book Judaism Discovered, Hoffman studied at the State University of New York at Oswego in the Finger Lakes region.

Hoffman supposedly was taught about William Morgan, whose disappearance in 1826 resulted in the formation of the Anti-Masonic Party by his maternal grandfather, who told him that elections in the United States were rigged by organized crime. From this, Hoffman was said to have deduced that "[n]othing is as it seems to be", which, in turn, led to a "life-long vocation, researching the subterranean workings of the occult cryptocracy's orchestration of American history".

In 1995, Hoffman moved with his family to northern Idaho. There, he hoped to establish a museum that would detail the "Communist holocaust against Christians" (i. e., the persecution of Christians in the Soviet Union), "the holocaust against the Germans", (i. e., the bombing of Dresden and other major German cities in World War II), and the "Holocaust against Japan" (i.,e., the bombing of Tokyo, and the atomic bombings of Hiroshima and Nagasaki).

Hoffman has written articles for the UK-based magazine Fortean Times, as well as the Lutheran newspaper Christian News of New Haven, Missouri. He claimed to have worked as a reporter for the Albany, New York, bureau of the Associated Press. His interests include the alleged occult roots of Freemasonry, the ideology of shadow government, Fortean phenomena, and traditional Judaism.

Hoffman has been described as a "Holocaust denier and anti-Semitic ideologue" by Michael Barkun of Syracuse University and Michael Whine. Swedish historian of Uppsala University Mattias Gardell has asserted: "Antisemitism is prominent... in the worldview of Michael Hoffman II".

Hoffman has worked on projects for now-deceased KKK Grand Dragon Tom Metzger, as well as "fellow travelers" Willis Carto, David Irving, Ernst Zündel, and Herman Otten. Hoffman was the Assistant Director of the Institute for Historical Review (IHR), a premier historical revisionist organization with a particular focus on Holocaust denial. Stephen E. Atkins, in his book, Holocaust Denial as an International Movement (2009), wrote that Hoffman's newsletter Revisionist History promotes Holocaust denial, and Hoffman contends that "the real Holocaust of World War II was deaths caused by the Allies". He quotes Hoffman denying the existence of the usage of gas chambers by Nazi Germany:

"[T]here is no material scientific proof for the existence of Nazi homicidal gas chambers. There are no autopsies available from any source showing that even one Jew died as a result of Zyklon B (hydrocyanic acid) poisoning, among the millions who are alleged to have been killed in this manner."
