Azougui (or Azuggi, Arabic: آزوكي) was a town in north-western Mauritania, lying on the Adrar Plateau, north-west of Atar.

In the eleventh century it was the first capital of the Almoravid dynasty,[1] who conquered a territory stretching from the Ghana Empire to Morocco and the Iberian Peninsula.

[2] Both of them Berber Sanhaja desert tribes and one-time allies, the Lamtuna formed the core of the Almoravids after the Gudala broke away.

It was near this location, at a place called Tabfarilla, that the early Almoravids suffered their first significant defeat, when the Gudala crushed an Almoravid Lamtuna army based in Azougui and killed their leader Yahya ibn Umar in 1056.

This site was added to the UNESCO World Heritage Tentative List on June 14, 2001, in the Cultural category.
