Cord Meyer Jr. (; November 10, 1920 – March 13, 2001) was a US Central Intelligence Agency (CIA) official. After serving in World War II as a Marine officer in the Pacific War where he was both injured and decorated, he led the United World Federalists in the years after the war. In about 1949, he began work with the CIA where he became a high-level operative, retiring in 1977. He married Mary Pinchot in 1945; the couple divorced in 1958, and she was subsequently romantically linked to President John F. Kennedy. Her 1964 murder remains both unsolved and controversial.
