Rharb (sometimes Gharb, in Arabic: غرب "west") is a historical and geographical region in northern Morocco.

History
Ibn Khaldun - historian and diplomat of the North Africa from the 14th and 15th centuries - has described:

« [le calife almohade] établit les Riah dans le Habt et les Jochem dans la Tamesna, vaste plaine qui s'étend de Salé à        Marrakech. »
