The Western al-Hasakah offensive was a military operation in the spring of 2015, waged between the Kurdish YPG and allied forces against the Islamic State (ISIL) for control of the western half of the Al-Hasakah Governorate, during the Syrian Civil War. The Syrian Kurds' counteroffensive was dubbed Operation Commander Rûbar Qamishlo. During the initial ISIL offensive, Islamic State forces managed to advance up to the western banks of the Khabur River, reaching Tell Tamer and Ras al-Ayn, and capturing dozens of villages, in addition to abducting 350–400 Assyrian Christians as hostages. In the subsequent Kurdish-led counteroffensive, the Kurdish-led forces managed to expel Islamic State forces from the western countryside of the al-Hasakah Governorate, in addition to the Abzulaziz mountain range. On 31 May 2015, as most of the offensive operations in the western Al-Hasakah Governorate ended, the part of the offensive in the Ras al-Ayn District expanded into the Tell Abyad region, in the northern Raqqa Governorate.
