Christian Archibald Herter (March 28, 1895 – December 30, 1966) was an American politician and statesman; 59th governor of Massachusetts from 1953 to 1957, and United States Secretary of State from 1959 to 1961.

Herter was born in Paris, France, to American artist and expatriate parents, Albert Herter and Adele McGinnis, and attended the École Alsacienne there (1901–1904) before moving to New York City, where he attended the Browning School (1904–1911). He graduated from Harvard University in 1915 and did graduate work in architecture and interior design before joining the diplomatic corps in the following year.

Herter married the wealthy heiress Mary Caroline Pratt (1895–1980) in 1917. She was the daughter of Frederic B. Pratt, longtime head of the Pratt Institute and granddaughter of Standard Oil magnate Charles Pratt. They had three sons and one daughter, including Christian A. Herter, Jr., who was active in international relations.

He was made attaché to the U.S. Embassy in Berlin, and he was briefly arrested while in Mainz as a possible spy. He was part of the U.S. delegation to the 1919 Paris Peace Conference, where he helped draft the Covenant of the League of Nations. Later, he was the assistant to Herbert Hoover when he was instrumental in providing starvation relief to post–World War I Europe and was later Commerce Secretary. Herter also participated in the 1919 meeting that resulted in the U.S. Council on Foreign Relations.
