The 2017 Mayadin offensive was a military offensive launched by the Syrian Arab Army against members of the Islamic State (IS) in the Deir ez-Zor Governorate, following the breaking of the three-year siege of the city of Deir ez-Zor. The Mayadin offensive, conducted by Syrian Army troops, was conducted with the aim of capturing IS's new de facto capital of Mayadin, and securing the villages and towns around it.
The offensive was concurrent with the Raqqa campaign conducted by the Syrian Democratic Forces (SDF) against IS's former de facto capital city and stronghold in Syria, as well as the Western Anbar campaign in Iraq.
