Princess Catherine Olympia Caradja (born Ecaterina Olimpia Creţulescu; 28 January 1893 – 26 May 1993) was a Romanian aristocrat and philanthropist. Born in Bucharest, she grew up in England and France, and lived in Romania from 1908 to 1952, when she escaped from the communist regime on a Danube boat. An expatriate in the United States for 35 years, and a longtime resident of the Hill Country of Texas, she returned after the Romanian Revolution of 1989 to Bucharest, where she died a centenarian.
