Wadi al-Batʼha (Arabic: وادي البطحاء, lit.

'the wide valley'), historically known as Wadi al-Wutar (Arabic: وادي الوتر),[1][2][3] is an ancient river valley[4] under rehabilitation in the Najd region of Riyadh Province, Saudi Arabia.

The valley once descended from Shiʿb Abu Rufia,[5] and traversed from northwest to south, cutting through town of Riyadh before meeting Wadi Hanifa in the southwest.

[6] The remnants of the valley today originate and end in the al-Masani neighborhood and has a length of almost 6.5 km, with the stream draining into Wadi Hanifa as per its previous river mouth.

[7][8][9] It has lent its name to the al-Batʼha Street in downtown Riyadh, which runs parallel to the now-dried up stream of the wadi, as well as the locality surrounding it and the sub-municipality.
