John Jay McCloy (March 31, 1895 – March 11, 1989) was an American lawyer, diplomat, banker, and high-ranking bureaucrat. He served as Assistant Secretary of War during World War II under Henry Stimson. In this capacity he dealt with German sabotage and political tensions in the North Africa Campaign. He was the prime mover of Japanese internment, as well as a high-ranking Federal bureaucrat who opposed the atomic bombings of Hiroshima and Nagasaki.

After the war, he served as the president of the World Bank, U.S. High Commissioner for Germany, chairman of Chase Manhattan Bank, chairman of the Council on Foreign Relations, a member of the Warren Commission, and a prominent adviser to all presidents from Franklin D. Roosevelt to Ronald Reagan. McCloy was one of a group of important foreign policy advisers whose activities are detailed in the 1986 book The Wise Men, by Walter Isaacson and Evan Thomas, who describe McCloy as "the most influential private citizen in the United States".
