Operation Inherent Resolve (OIR) is the U.S. military's operational name for the military intervention against the Islamic State of Iraq and Syria (ISIL, in the vernacular, Daesh), including both the campaign in Iraq and the campaign in Syria. Since 18 September 2018, the U.S. Army's III Armored Corps has been responsible for Combined Joint Task Force – Operation Inherent Resolve (CJTF—OIR). The campaign is primarily waged by American air forces in support of local allies, most prominently the Iraqi security forces and Syrian Democratic Forces. Combat ground troops, mostly special forces and artillery, have also been deployed, especially in Iraq. 75-80% of the airstrikes have been conducted by the military of the United States, with the other 20-25% by the United Kingdom, France, Turkey, Canada, the Netherlands, Denmark, Belgium, Saudi Arabia, the United Arab Emirates, and Jordan.

By October 2017, around the time of ISIL's territorial defeat in Iraq, CJTF-OIR claimed that around 80,000 ISIL militants had been killed in all actions excluding those targeted by Russian and Syrian strikes.
