Julius Klein (1901–1984) was an American journalist, spy, business executive and United States Army general.
Klein also originated the South Pacific edition of The Stars and Stripes military newspaper, unsuccessfully ran for Congressman at Large as Republican in 1932, and for the United States Senate in 1954.
He wrote the screenplay, Black Cargo, during a Hollywood stint (1934–39) when Klein tried unsuccessfully to produce films on the life of General John Pershing.
During this time Klein also worked as a journalist for the Chicago Herald-Examiner, published his own periodical (The National Free Press) with his nephew Joseph Roos, and conducted domestic intelligence gathering and spy operations authorized by both Illinois governor Henry Horner and Colonel (later General) George C.
On April 4, 1948, as National Commander of the Jewish War Veterans, Klein organized an enormous show of strength for the establishment of the State of Israel in the form of a JWV parade down New York's Fifth Avenue.
