The Kadisha Valley (also known as Qadisha Valley, Wadi Qadisha, Ouadi Qadisha, or وادي قاديشا in Arabic) is a valley that lies within the Becharre and Zgharta Districts of the North Governorate of Lebanon. The valley is a deep gorge carved by the Kadisha River, also known as the Nahr Abu Ali when it reaches Tripoli. Kadisha means "Holy" in Aramaic, and the valley, sometimes called the Holy Valley, has sheltered Christian monastic communities for many centuries.
