The Eastern Syria insurgency is an armed insurgency being waged by remnants of the Islamic State of Iraq and the Levant (ISIL) and both pro and anti-Syrian government Arab nationalist insurgents, against the Autonomous Administration of North and East Syria, its military (the Syrian Democratic Forces (SDF)), and their allies in the US-led Combined Joint Task Force – Operation Inherent Resolve (CJTF–OIR) coalition.
The insurgency began after a series of campaigns in 2016 and 2017 which took territory from the Islamic State of Iraq and the Levant, led by the Syrian Democratic Forces and the CJTF-OIR. This eventually resulted in the taking of the Islamic State capital of Raqqa, and other areas in the Aleppo, Raqqa and Deir ez-Zor Governorates. These are Arab-majority areas, often with large Turkmen minorities, some of whom resented the Kurdish influence in the SDF.
Multiple factions, made up mostly of Arabs, have formed armed groups in support of either the Syrian opposition or Syrian government, with additional Islamic State remnants operating as clandestine cells who have emerged in areas captured by the SDF and the coalition during the 2016-2017 campaigns. These groups have also utilized guerilla tactics to target the SDF and Coalition forces, including assassinations, hit and run attacks, rocket attacks and use of improvised explosive devices (IEDs). Attacks have occurred in cities across Rojava, including Manbij, Raqqa and Hasakah.
- Islamic State of Iraq and the Levant: Following the loss of most of its territory, the Islamic State of Iraq and the Levant has launched a desert-based insurgency, while simultaneously attempting to rally elements of the civilian population to its cause. By attacking SDF-backed civil authorities, it undermines the latter's reputation and worsens existing grievances, resulting in a deteriorating security situation. It is unclear how many active ISIL fighters still operate in Syria, but they probably number several thousands.
- Government loyalists: Various pro-government groups operate in eastern Syria, including the "Popular Resistance of the Eastern Region" (founded in February 2018 in Raqqa), the "Popular Resistance in Hasakah" (founded in April 2018), and the "Popular Resistance in Manbij" (founded in June 2018). These groups are reportedly supported by Iran, and elements of the Syrian Armed Forces such as the Baqir Brigade.

By the end of October, the U.S. had adopted a subordinate mission to protect SDF-controlled oil and gas infrastructure, including oil fields, from the ISIL insurgency as the insurgent group had previously used profits from oil smuggling to fund its activities.
