Erg Chebbi (Arabic: ÚÑÞ ÇáÔÈíý) is the sole Saharan erg in Morocco.

The erg is 22 km long (North-South) and 5 km wide. Its dunes reach a maximum height of 150 meters. It is located roughly 40 kilometers south-east of Erfoud. The local center for tourists is the village of Merzouga. Supposedly, the locals believe that these dunes were sent as a punishment for turning away a weary traveller from the desert. They say that after they sent away this traveller, the gods made the dunes pile up right outside their town; to teach them a lesson and to never send away weary men and women ever again.
