The 2017 Western Iraq campaign was the final major military operation of the 2013–2017 war in Iraq, in the western province of Anbar, and on the border with Syria, with the goal of completely expelling ISIL forces from their last strongholds in Iraq.

The offensive followed the Hawija offensive by the Iraqi Government, and was also concurrent with several major offensives in Syria: the Syrian Democratic Forces' Deir ez-Zor offensive, and the Syrian Government's Battle of Deir ez-Zor and Eastern Syria campaign on the opposite side of the Al-Qa'im border crossing.

Background 

Al-Qa'im was known as a hotbed of jihadist insurgency, after the 2003 invasion of Iraq, with coalition forces carrying out repeated operations against Al-Qaeda jihadists. The strategic and porous border started becoming a route for foreign fighters entering Iraq from Syria, who was accused by Iraqi Government of ignoring it.

The towns of western Anbar were captured by the Islamic State of Iraq and the Levant in 2014. Before the 2017 offensive, Iraqi forces had dislodged the group from key cities of Anbar including Ramadi and Fallujah but the areas near border with Syria including Anah, Rawa, Al-Qaim left and the vast rural areas across the province remained under militant control. An Iraqi operation was launched towards west Anbar in January 2017, but was suspended after recapture of towns of Sagra and Zawiya because of preparations for retaking the western bank of Mosul.

In September 2017, the Iraqi Army launched an offensive in the western Anbar Province, recapturing the towns of Akashat on 16September and Anah on 21September. After recapturing Hawija on 5October Iraqi Army was expected to fight ISIL in Anbar. Instead, it paused its military actions and later started advancing on Kirkuk.
