Tell el-'Oueili (also Awayli; Mesopotamian Arabic: تل العويلي, romanized: Təll əl-ʿOwēli) is a tell, or ancient settlement mound, located in Dhi Qar Governorate, southern Iraq. The site was excavated between 1976 and 1989 by French archaeologists under the direction of Jean-Louis Huot. The excavations have revealed occupation layers predating those of Eridu, making Tell el-'Oueili the earliest known human settlement in Lower Mesopotamia.
