The Rif or Riff (Berber:ⴰⵔⵉⴼ Arif, Arabic: جبال الريف) is a mainly mountainous region of northern Morocco, with some fertile plains, stretching from Cape Spartel and Tangier in the west to Ras Kebdana and the Melwiyya River in the east, and from the Mediterranean in the north to the river of Wergha in the south.
It is part of the Cordillera Bética that also includes the mountains of Southern Spain. The Rif mountains are not part of the Atlas Mountains but belong to the Gibraltar Arc or Alborán Sea geological region.
The region's name comes from the Berber word Arif. Major cities in the greater Rif region include Nador, Tangiers, Al Hoceima (also called Biya), Azghenghan, Selwan, Aâarwi, Imzouren, Ajdir, Targuist (Targist), Tittawin, Berkan, Taza, Tawrirt, and El Jebha.
