David Shub (Yiddish: דוד שוב, Russian: Давид Натанович Шуб, romanized: David Natanovich Shub) (13 September 1887 – 27 May 1973) was a Russian-born Jewish-American social democratic activist, journalist, and historian.
In 1930 he wrote the lead article on Stalin, probably the first authoritative profile to appear in the American press, for The New York Times Magazine (22 March 1930). His 1948 biography of Lenin has been reprinted over sixteen times, described as "indispensable to the student of contemporary history, of Russia, and of social revolution."
