Ross John Swartz Hoffman (February 2, 1902 - December 16, 1979) was an American historian, writer, educator, and conservative intellectual who specialized in Modern European History and International Affairs.

His doctoral dissertation ("Great Britain and the German Trade Rivalry, 1875-1914"), prepared under the supervision of William Ezra Lingelbach, was published by the University of Pennsylvania Press in 1933 and received the George Louis Beer Prize from the American Historical Association in 1934.

[3] Hoffman published articles and books on both current and historical events, and contributed to a short-lived conservative journal, The American Review.

[2] Several of Hoffman's books dealt with world events: The Will to Freedom (Sheed, 1935); Tradition and Progress, and Other Historical Essays in Culture, Religion, and Politics (Bruce Books, 1938); The Organic State: An Historical View of Contemporary Politics (Sheed, 1939); The Great Republic: A Historical View of the International Community and the Organization of Peace (Sheed, 1942); (with C. G. Haines) Origins and Background of the Second World War (Oxford University Press, 1943; 2nd edition, 1947); Durable Peace: A Study in American National Policy (Oxford University Press, 1944); and The Spirit of Politics and the Future of Freedom (Bruce Books, 1951).

He was the recipient of a Festschrift from former students and other admirers, Crisis in the "Great Republic": Essays Presented to Ross J. S. Hoffman, edited by Gaetano L. Vincitorio and James E. Bunce et al. (Fordham University Press, 1969).
