The Ziz River (Arabic: وادي زيز wadī zīz or نهر زيز nahr zīz) is a river in the south of Morocco and Algeria. It has its source in the High Atlas mountains of Morocco and flows 282 kilometers (175 mi) into the Sahara Desert in Algeria. Although water flow is intermittent along the Ziz riverbed, its watercourse has long been used to facilitate human transit through the mountainous region.

Cities along the Ziz river include Errachidia, Erfoud and Sijilmassa. There is a dam (Hassan Ad Dakhil dam) on the Ziz river near Errachidia that supplies drinking and irrigation water for the valley, supported by multiple downstream diversion dams for agricultural use.
