Wadi Hanifa (Arabic: وَادِي حَنِيْفَة, romanized: Wādī Ḥanīfah), historically known as Wadi al-Arad,^[1] is a wadi (seasonal river) in the Najd region, Riyadh Province, in central Saudi Arabia. The valley runs for a length of 120 km (75 mi) from northwest to southeast, cutting through the city of Riyadh, the capital of Saudi Arabia. A string of towns and villages lie along the valley, including Uyaynah, Irqah and Diriyah. The historical city of Riyadh itself is on the northeastern side of the wadi, but the city has now expanded across Wadi Hanifa, with the sub-municipalities of Al-Shifa and Al-Urayja on its southwestern side.
