Leon Lazarus (August 22, 1919 – November 28, 2008) was an American writer-editor for publisher Martin Goodman's Magazine Management Company, as well as for Goodman's Timely and Atlas comic book companies, the two predecessors of Marvel Comics. The uncredited author of countless comic-book stories from 1947 through at least 1965 – with his name long considered a possible pseudonym on the rare occasions it appeared – the 85-year-old Lazarus was located in 2005 by comics historians who then initiated efforts to document his credits and fill some of the many gaps in the medium's record.
