The Supreme Military Council (SMC) was the highest military leadership of the Free Syrian Army (FSA) from late 2012 to at least mid-2014. The establishment of the organisation was announced on 7 December 2012 with the backing of western and Arab powers as a means of financing and arming Syrian rebel forces.

The Free Syrian Army is a big-tent coalition of decentralized Syrian opposition armed militias in the Syrian Civil War founded on 29 July 2011 by Colonel Riad al-Asaad and six officers who defected from the Syrian Armed Forces. The officers announced that the immediate priority of the Free Syrian Army was to safeguard the lives of protestors and civilians from the deadly crackdown by Bashar al-Assad's security apparatus; with the ultimate goal of accomplishing the objectives of the Syrian revolution, namely, the end to the decades-long reign of the ruling al-Assad family. In late 2011, the FSA was the main Syrian military defectors group. Initially a formal military organization at its founding, its original command structure dissipated by 2016, and the FSA identity has since been used by various Syrian opposition groups.
