The 1963 Syrian coup d'état, referred to by the Syrian government as the 8 March Revolution, was the seizure of power in Syria by the military committee of the Syrian Regional Branch of the Arab Socialist Ba'ath Party. The planning and the unfolding conspiracy of the Syrian Ba'athist operatives were prompted by the Ba'ath party's seizure of power in Iraq in February 1963.

The Arab Socialist Ba'ath Party – Syria Region, officially the Syrian Regional Branch, is a neo-Ba'athist organisation founded on 7 April 1947 by Michel Aflaq, Salah al-Din al-Bitar and followers of Zaki al-Arsuzi. The party has ruled Syria continuously since the 1963 Syrian coup d'état which brought the Ba'athists to power. It was first the regional branch of the original Ba'ath Party (1947–1966) before it changed its allegiance to the Syrian-dominated Ba'ath movement (1966–present) following the 1966 split within the original Ba'ath Party. Since their ascent to power in 1963, neo-Ba'athist officers proceeded by stamping out the traditional civilian elites to construct a military dictatorship operating in totalitarian lines; wherein all state agencies, party organisations, public institutions, civil entities, media and health infrastructure are tightly dominated by the army establishment and the Mukhabarat.
