This article is a list of armed groups involved in the War in Iraq (2013–2017). The war started in 2013, following the 2011–2013 insurgency, and ended in 2017 although it continued as a low-level insurgency. The Islamic State of Iraq and the Levant (ISIL) had a major involvement during the war, until it was militarily defeated in Iraq in December 2017. Baathist supporters and some Sunni groups fought against the Government of Iraq and its allies. The Peshmerga fought against ISIL and other forces during the war; though not against the government, they did not join the Iraqi forces. There are ongoing negotiations related to the future of Iraqi Kurdistan, internal and external conflicts, and the security of the country and the region.
