Dadès River (Arabic: وادي دادس, romanized: Wādī Dādis; French: Oued Dadès; Amazigh: ⴰⵙⵉⴼ ⵏ ⴷⴰⴷⵙ, romanized: Asif n Dads) is a river in Morocco.

The Dadès River rises in the High Atlas and then turns south crossing through the Dadès Gorges, then westward between the High Atlas and Anti-Atlas mountain ranges.

Dades Gorge is easily accessible by taxi from nearby Tinerhir.

The valley itself is made lush and green by the river, while the surrounding area is rocky desert.

Women can be seen washing laundry in the river and laying it to dry on the surrounding bushes.
