Hassaniya Arabic or simply Hassānīya (Arabic: حسانية Ḥassānīya; also known as Hassaniyya, Klem El Bithan, Hasanya, Hassani, Hassaniya) is a variety of Maghrebi Arabic spoken by Mauritanian Arab-Berbers and the Sahrawi. It was spoken by the Beni Ḥassān Bedouin tribes, who extended their authority over most of Mauritania and Morocco's southeastern and Western Sahara between the 15th and 17th centuries. Hassaniya Arabic was the language spoken in the pre-modern region around Chinguetti.
