The Reguibat (Arabic: الرقيبات; variously transliterated Reguibate, Rguibat, R'gaybat, R'gibat, Erguibat, Ergaybat) is a Sahrawi tribe of Sanhaja-Berber origins. The Reguibat speak Hassaniya Arabic, and are Arabized in culture. They claim descent from Sidi Ahmed Rguibi, who lived in the Saguia el-Hamra region in the 16th century. They also believe that they are, through him, a chorfa tribe, i.e. descendants of Muhammad. Religiously, they belong to the Maliki school of Sunni Islam.
