Supreme Headquarters Allied Powers Europe (SHAPE) is the headquarters of the North Atlantic Treaty Organization's Allied Command Operations. Since 1967 it has been located at Casteau, north of the Belgian city of Mons, but it had previously been located, from 1953, at Rocquencourt, next to Versailles, France. From 1951 to 2003, SHAPE was the headquarters of Allied Command Europe, ACE. Since 2003 it has been the headquarters of Allied Command Operations (ACO), controlling all NATO operations worldwide.

SHAPE retained its traditional name with reference to Europe for legal reasons although the geographical scope of its activities was extended in 2003. At that time, NATO's command in Lisbon, historically part of the Atlantic command, was reassigned to ACO. The commander of Allied Command Operations has also retained the title "Supreme Allied Commander Europe" (SACEUR), and continues to be a U.S. four-star general officer or flag officer who also serves as Commander, U.S. European Command.

An integrated military structure for NATO was first established after the Korean War raised questions over the strength of Europe's defences against a Soviet attack. The first choice for commander in Europe was American General of the Army Dwight D. Eisenhower, as he had successfully directed the Allied landings in Normandy and subsequent march into Germany during World War II, amid many inter-Allied controversies over the proper conduct of the campaign on the Western Front. On December 19, 1950, the North Atlantic Council announced the appointment of General Eisenhower as the first SACEUR. British Field Marshal Sir Bernard L. Montgomery moved over from the predecessor Western Union Defence Organization (WUDO) to become the first Deputy SACEUR, who would serve until 1958. Volume 3 of Nigel Hamilton's Life of Montgomery of Alamein gives a good account of Montgomery's exacting, tireless approach to improving the command's readiness, which caused a good deal of bruised feelings in doing so. In establishing the command, the first NATO planners drew extensively on WUDO plans and personnel.
