List of armed groups in the War in Iraq (2013–2017)

This article is a list of armed groups involved in the War in Iraq (2013–2017). Part of the Iraqi conflict, the war escalated in 2013, following a 2011–2013 insurgency and the rise of the Islamic State. Following the liberation of much of Islamic State-held territory in 2017, only a low-level insurgency continued after. The Islamic State had a major involvement during the war, until it was militarily defeated in Iraq by Iraqi and western coalition forces in December 2017. Baathist supporters and some Sunni groups also fought against the Government of Iraq and its allies. The Peshmerga fought against the Islamic State and other forces during the war; though not against the government, and they did not join the Iraqi forces.
