The "X Article" is an article, formally titled "The Sources of Soviet Conduct", written by George F. Kennan and published under the pseudonym "X" in the July 1947 issue of Foreign Affairs magazine. It widely introduced the term "containment" and advocated for its strategic use against the Soviet Union. It expanded on ideas expressed by Kennan in a confidential February 1946 telegram, formally identified by Kennan's State Department number, "511", but informally dubbed the "long telegram" for its size.
