Ma'tan as-Sarra is an oasis in the Kufra District municipality in the southeast corner of Libya. It is located in the Libyan Desert, 322 kilometres (200 mi) southwest of Kufra. A marginal oasis, with few palms and substandard water, it allowed the creation in 1811 of the last trans-Saharan caravan route. However, it historically has been little visited by Toubou and Zaghawa nomads.
