Constantin Argetoianu (1871 – February 6, 1952) was a Romanian politician, one of the best-known personalities of interwar Greater Romania, who served as the Prime Minister between September 28 and November 23, 1939. His memoirs, Memorii. Pentru cei de mâine. Amintiri din vremea celor de ieri ("Memoirs. For those of tomorrow. Recollections of yesterday's world")—a cross section of Romanian society, were made known for the sharp critique of several major figures in Romanian politics (using a sarcastic tone which had made his previous political speeches notorious).
