Terjit (Arabic: ترجيت) is an oasis (in the proper sense: a desert spring or other water source), 45km by road south of Atar and popular with tourists in Mauritania.

It nestles in a gorge on the western edge of the Adrar plateau with the palm grove stretching a few hundred meters alongside a stream which emerges from a spring.

Terjit is part of the commune of Maaden in the Aoujeft Department.

[1] There is a modest fee to enter, and tourists can pay to stay in tents in the palm grove.

It is often used for tourism for its charm, fresh water and shade.
