Henry Cabot Lodge, Jr. (July 5, 1902 - February 27, 1985) was a United States Senator from Massachusetts, a U.S. ambassador, and a candidate for Vice President of the United States. He was the grandson of famous statesman Henry Cabot Lodge.

Elected to the Senate as a Republican in 1936, he served until 1944, when he quit to go on active service in the army in World War II, the first senator to do so since the Civil War. He served with distinction, rising to the rank of lieutenant colonel, and was elected once again to the Senate in 1946.

In 1952 he was defeated in his bid for reelection by Congressman John F. Kennedy, and in 1953, he was named U.S. ambassador to the United Nations by President Dwight D. Eisenhower. He left the position during the election of 1960 to run for Vice President on the Republican ticket headed by Richard M. Nixon. The duo lost the election to Lodge's old foe, Kennedy. Kennedy appointed Lodge to the position of Ambassador to South Vietnam, which he held from 1963 to 1964.

In 1964, Lodge was the surprise write-in victor of the Republican New Hampshire primary, defeating declared candidates Barry Goldwater and Nelson Rockefeller. He was re-appointed ambassador to South Vietnam by President Lyndon B. Johnson in 1965, and served thereafter as Ambassador at Large (1967-1968) and Ambassador to West Germany (1968-1969). In 1969, he was appointed by President Richard Nixon to serve as head of the American team at the Paris peace negotiations, and he served as Special Envoy to the Vatican from 1970 to 1977.
