盟军远征部队最高司令部（英语：Supreme Headquarters Allied Expeditionary Force），英文缩写为「SHAEF」（英语发音：/ˈʃeɪf/），是盟军军队指挥官在欧洲西北部的司令部。SHAEF由1943年底开始运作，直到第二次世界大战欧战部份完结后于1945年7月解散，期间一直由美国派出的德怀特·D·艾森豪威尔将军领导。

Supreme Headquarters Allied Expeditionary Force (SHAEF; /ˈʃeɪf/ SHAYF), was the headquarters of the Commander of Allied forces in north west Europe, from late 1943 until the end of World War II. U.S. General Dwight D. Eisenhower was in command of SHAEF throughout its existence. The position itself shares a common lineage with Supreme Allied Commander Europe and Atlantic, but they are different titles.
