Mohammed Ziad al-Hariri (born 1930) is a former prominent Syrian Army officer. A staunch Arab nationalist, he supported the union between Syria and Egypt in 1958, opposed Syria's secession from it in 1961 and served as the chief leader of the coup d'état that toppled the secessionist government in March 1963. Politically independent from the Nasserists and their Ba'athist rivals, Hariri served as the army's chief of staff following the coup and was briefly defense minister until being dismissed during a wide-scale purge of non-Ba'athists from the military. He retired from political activity soon afterward.
