The Syrian Islamic Liberation Front (SILF; Arabic: جبهة تحرير سوريا الإسلامية, "Jabhat Tahrīr Sūriya al-Islāmiyyah") was a coalition of Syrian Islamist rebel groups nominally under the command of the Supreme Military Council of the Free Syrian Army that fought against the Syrian government in the Syrian Civil War. At the end of 2012, it was one of the strongest rebel coalitions in Syria, representing up to half of the rebel forces.
