The 2017 Euphrates Crossing offensive was a military offensive launched by the Syrian Arab Army against members of the Islamic State of Iraq and the Levant (ISIL) in the Deir ez-Zor Governorate, following the breaking of the three-year siege of the city of Deir ez-Zor. The Euphrates Crossing offensive, conducted by government troops, was done with the aim of denying US-backed Syrian Democratic Forces and the US itself leverage over the Syrian government.

The offensive was concurrent with the two SDF offensives, the Battle of Raqqa and the northern Deir ez-Zor offensive, as well the Hawija Offensive in Iraq.
