Ténès (Arabic: تنس; from Berber TNS 'camping') is a town in Algeria located around 200 kilometers west of the capital Algiers.

[6] The city prospered in spite of an unhealthy climate owing to the fertility of the surrounding countryside, which produced fruit and grain in relative abundance.

[6] Ténès was sacked by Oruç Reis in 1517 and conquered for the Ottoman Empire by his brother Hayreddin Barbarossa a few years later.

[6] Following the French invasion of Algiers in 1830, Ténès fell under the control of the Emir Abdelkader, who tried to revive its port.

[8] Its harbor about 1.5 km distant originally served as a port for goods from the Chelif, but declined following the construction of the Algiers–Oran railway.

It has some antique sites such as the Phoenician and Roman tombs, the prehistoric caves in Sidi Merouane, the Great Mosque of Sidi Ahmed Boumaza[9] (built some 11 centuries ago), Bab El Bahr, Notre Dame de Ténès, The French cannons, along with many others.
