The al-Mu'tasim Brigade ((Arabic: لواء المعتصم‎‎, Liwa' muetasim) is a Free Syrian Army faction active in the northern Aleppo Governorate, based in the town of Mare'. The group is named after al-Mu'tasim, an Abbasid caliph.

The Mu'tasim Brigade is known for possessing a large amount of US-supplied weapons from the Syrian Train and Equip program, including M16 rifles, M249 light machine guns, M240 machine guns, Soltam K6, M224 mortars, M252 mortars, M2 Browning, and technicals. This led to reports being made that this group is supplied by the United States. The group did not receive anti-tank missiles from the US.
