Mureybet is a tell, or ancient settlement mound, located on the west bank of the Euphrates in Raqqa Governorate, northern Syria. The site was excavated between 1964 and 1974 and has since disappeared under the rising waters of Lake Assad. Mureybet was occupied between 10,200 and 8,000 BC and is the eponymous type site for the Mureybetian culture, a subdivision of the Pre-Pottery Neolithic A (PPNA). In its early stages, Mureybet was a small village occupied by hunter-gatherers. Hunting was important and crops were first gathered and later cultivated, but they remained wild. During its final stages, domesticated animals were also present at the site.

The Euphrates is the longest and one of the most historically important rivers of Western Asia. Together with the Tigris, it is one of the two defining rivers of Mesopotamia. Originating in Turkey, the Euphrates flows through Syria and Iraq to join the Tigris in the Shatt al-Arab in Iraq, which empties into the Persian Gulf.
