The Ouergha River or Oued Ouerrha (Berber: Asif n Wergha; Arabic:واد ورغة) is a watercourse in Morocco that is a tributary to the Sebou River.

The Ouergha River was the site of a key battle in 1925, in which the French attempted to invade the Rif. However despite its significant military power, the French troops could not defeat the Rifian Berber tribal coalition.

In the upper parts of the watershed within the Middle Atlas is the prehistoric range of the endangered primate Barbary macaque, which prehistorically had a much larger range in North Africa.
