John Louis Spivak (June 13, 1897 – September 30, 1981) was an American socialist and later communist reporter and author, who wrote about the problems of the working class, racism, and the spread of fascism in Europe and the United States. Most of his writings date from the 1920s and 1930s. He lived under a pseudonym during the 1950s and 1960s, emerging again to publish his autobiography in 1967 and work as a journalist in the 1970s.
