Hubert Renfro Knickerbocker (January 31, 1898 – July 12, 1949) was an American journalist and author; winner of the 1931 Pulitzer Prize for Correspondence for his series of articles on the practical operation of the Five Year Plan in the Soviet Union.

On December 1, 1930, Knickerbocker interviewed Soviet leader Joseph Stalin's mother, Keke Geladze, in Tbilisi for the New York Evening Post through a Georgian interpreter.

In 1931, as a correspondent for the New York Evening Post and the Philadelphia Public Ledger, he won the Pulitzer Prize for "a series of articles on the practical operation of the Five Year Plan in Russia".

Like other foreign reporters, his work was progressively hampered by the rebel authorities, who finally arrested Knickerbocker in April 1937 and deported him shortly after.

Back to the United States, he wrote an article for the Washington Times, published on 10 May 1937, in which he exposed the brutal repression and the "antisemite, misogynist and antidemocratic" society that the Nationalists planned to develop, according to the statements by Francoist Foreign Press Liaison Officer Gonzalo de Aguilera Munro.

He was on assignment with a team of journalists touring Southeast Asia when they were all killed in a plane crash near Bombay, India (modern day Mumbai), on July 12, 1949.
