Which river flows through Cairo, Egypt?

The Nile is the river that flows through Cairo, Egypt.

Cairo stands on the Nile's eastern bank in northern Egypt, close to the river's transition into the fertile Nile Delta. The river has supported settlements, farming, transport, and political power in northeastern Africa for thousands of years. Ancient Egyptian civilization depended on its predictable agricultural cycle, although modern dams now regulate much of the flow.

The Nile is commonly described as the world's longest river, although measurements and comparisons with the Amazon have produced scientific debate. Its two principal tributaries are the White Nile, whose headwaters are associated with the Great Lakes region, and the Blue Nile, which rises in Ethiopia and contributes much of the seasonal water and sediment.

Cairo is not at the river's mouth: the Nile continues north from the city through the delta before reaching the Mediterranean Sea. The river's name comes through Greek and Latin forms related to the ancient Egyptian river name.
