The 2024 Deir ez-Zor offensive occurred in December 2024 when the Syrian Democratic Forces, backed by US-led coalition aircraft, launched an offensive against pro-regime forces in eastern Deir ez-Zor Governorate, Syria.
In November 2024, as the Syrian Civil War was reignited by the Turkish-backed rebels' "Deterrence of Aggression" offensive in Idlib Governorate, clashes broke out between ISIL cells and the Syrian Democratic Forces - as well as between United States forces and Iranian-backed militias - in eastern Syria. Amid heightened regional tensions, Iranian-aligned militias significantly expanded their military presence and security operations in al-Bukamal, and Iran dispatched reinforcements from Kata'ib Hezbollah, the Popular Mobilization Units, and Liwa Fatemiyoun to aid the crumbling Syrian Arab Army in fighting back the rebels. On 30 November, Russian forces withdrew military equipment and personnel from multiple headquarters across the Seven Villages area and retreated to Deir ez-Zor.
On 3 December 2024, the Syrian Democratic Forces launched an offensive on pro-government forces near the towns of Khasham and al-Salihiyah, and American-led coalition aircraft targeted Iran-backed militias to aid the Kurdish advance. On 5 December, government forces withdrew from Resafa and the Thawra oil field, and, on 6 December, the SDF occupied Deir ez-Zor, Mayadin, al-Quriyah, and Abu Kamal as government forces retreated.
