Walwal (Amharic: ወልወል; Arabic: ويلويل; Italian: Ual-Ual; also transliterated as Welwel or Walwaal) is a town in eastern Ethiopia known as the Ogaden.

Located in the Werder Zone of the Somali Region, this town has a longitude and latitude of 7°03′N 45°24′E / 7.050°N 45.400°E / 7.050; 45.400 with an elevation of 570 meters above sea level.

The control of this region allowed the Dervish to count, even in the most critical moments, on a source of animal supply, also collected in the form of a tribute, taking it away from the traditional authorities.

[1] Walwal was the oasis in Ethiopia where a border clash occurred in 1934 between the Kingdom of Italy and Ethiopian Empire.

Benito Mussolini used this incident as a pretext to invade Ethiopia, which led to the Second Italo-Abyssinian War.
