Ralph G. Martin (March 4, 1920 – January 9, 2013) was an American journalist who authored or co-authored about thirty books,[1] including popular biographies of recent historical figures, among which, Jennie, a two-volume (1969 and 1971) study of Winston Churchill's American mother, Lady Randolph Churchill, became the most prominent bestseller.

He studied at City College of New York before earning a bachelor's degree in journalism from the University of Missouri in 1941.

In December, following declaration of war in the aftermath of attack on Pearl Harbor, Martin enlisted in the Army and spent the war as a combat correspondent for the Armed Forces newspaper Stars and Stripes and the Army weekly magazine, Yank.

During the months preceding the 1952 and 1956 presidential elections, he served as a member of the campaign staff for the Democratic nominee, Adlai Stevenson.
