The Islamic Front was a Sunni Islamist rebel group involved in the Syrian Civil War, which was formed by the union of seven separate groups on 22 November 2013. Its three largest components were Ahrar ash-Sham, the al-Tawhid Brigade and Jaysh al-Islam. The alliance was achieved by expanding the preceding Syrian Islamic Front alliance. It was described as "an umbrella organization rather than a full union", with constituent factions continuing to serve under their own distinct leaderships.

The al-Tawhid Brigade, named after Tawhid, the "oneness of God," was an armed Islamist insurgent group involved in the Syrian Civil War.
