Prince Gheorghe Grigore Cantacuzino

Gheorghe Grigore Cantacuzino (22 September 1832 – 23 March 1913), was a Romanian politician and lawyer, one of the leading Conservative Party policymakers. He was an aristocrat and member of the House of Cantacuzino.

Among Cantacuzino's political posts were that of Minister of Public Instruction, president of the Chamber of Deputies, and President of the Senate. He twice served as the Prime Minister of Romania: between 23 April 1899 and 19 July 1900, and between 4 January 1906 and 24 March 1907. He resigned from office after failing to put down the large-scale peasants' revolt. He was the 20th Romanian politician to serve as Prime Minister.

The wealthy Cantacuzino was born into the aristocratic Cantacuzino family, of Phanariote origins. He built the Cantacuzino Palace of Bucharest and the Cantacuzino Castle of Bușteni. He was the father of Grigore Gheorghe Cantacuzino and Mihail G. Cantacuzino, as well as the father-in-law of Alexandrina Pallady-Cantacuzino.
