Tadjenanet (Arabic : تاجنانت, Tamazight: ⵜⴰⴵⵏⴰⵏⵜ), formerly called Saint-Donat, is a town and commune in Mila Province, Algeria.

The colonial village of Saint-Donat, known as Tadjenanet today, was established in 1872 on the lands of the municipality of Oued Athmania, on the edge of the Tadjnit Valley.

Instead, it is derived from "Taqqennant" or "Tayennant," meaning a flat land, as it sits on an expanse of entirely level terrain.

Indeed, the vast majority of the inhabitants of Tadjenanet call themselves "Arabized" chaouis and consider that the city is in a sense an integral part of the Aurès, in particular in relation to the proximity of the wilaya of Batna.

Founded in 1971, the club achieved a significant milestone in its history in 2015 when it secured a spot in the National Division 1, marking its debut in the elite football league of Algeria.
