Erfoud (Berber languages: ⴰⵔⴼⵓⴷ, Arfud; Arabic: أرفود) is an oasis town in the Sahara Desert, in the Drâa-Tafilalet region, eastern Morocco.

Due to its proximity to Merzouga desert village in the Erg Chebbi Dunes, Erfoud has developed tourist-related infrastructures such as hotels and restaurants.

Erfoud's Jewish community traced its roots to the French protectorate period in the early 20th century, when several hundred individuals from nearby towns, particularly El Mâadid, settled in the region encouraged by French plans to develop the town.

[1] Following Morocco's independence in 1956, the majority of Erfoud's Jewish population emigrated, mainly to Israel.

In February 2013 the Austrian Space Forum spent the whole month with a field team including two space suit simulators (Aouda.X and Aouda.S) and a number of rovers to conduct a large number of experiments.
