The Oued Fes (Arabic: واد فاس, lit. 'River of Fes') or Fez River is a river in Morocco. It is a tributary of the Sebou River and historically the main source of water for Morocco's second largest city, Fes, after which it is named.
The river consists of a number of different streams which originate in the Saïss Plain to the south and west of Fes before joining together in the area of Fes el-Bali, the old city (medina) of Fes. Over the centuries the river has been split and diverted into a multitude of canals that distributed water across the city and once powered a number of historic waterwheels. These various water channels converge into the Oued Bou Khrareb which runs through the middle of the old city and historically divided the Qarawiyyin and Andalusiyyin quarters. After the river leaves the city it runs eastwards for a short distance before joining the Sebou River. The various branches and sections of the river, including many of the man-made canals, also have their own names.
