The Ouergha River (Berber: Asif n Wergha) is a watercourse in Morocco that is tributary to the Sebou River.
The Ouergha River was a key battle site in the French invasion of Morocco in the year 1924. The French, encouraging the fighting of native Moroccan tribes among each other, advanced with 12,000 troops to a crossing of the Ouergha and achieved a major victory here without a shot being fired.
In the upper parts of the watershed within the Middle Atlas is the prehistoric range of the endangered primate Barbary macaque, which animal prehistorically had a much larger range in North Africa.
