Ras al-Ayn, also spelled Ras al-Ain, is a city in al-Hasakah Governorate in northeastern Syria, on the Syria–Turkey border.

Al-Hasakah Governorate is one of the fourteen governorates (provinces) of Syria. It is located in the far north-east corner of Syria and distinguished by its fertile lands, plentiful water, natural environment, and more than one hundred archaeological sites. It was formerly known as Al-Jazira Province. Prior to the Syrian Civil War nearly half of Syria's oil was extracted from the region. It is the lower part of Upper Mesopotamia.
