Ubari is a Tuareg-speaking oasis town and the capital of the Wadi al Hayaa District in Libya.
It is in the Idehan Ubari, a Libyan section of the Sahara Desert. Ubari is in the Targa valley, lying between the Messak Sattafat plateau and Idhan Ubari erg sand dunes and lakes. Native plants include wetland grasses at the natural spring fed lakes' shorelines, and the native Saharan Date palm (Phoenix dactylifera)
The Ubari oasis settlement is the second center for the Kel Ajjer Tuareg people, after Ghat. Neighbouring villages include Germa, and Garran.
