Diffa Arabs (Arabic: عرب الديفا) (also known as Mahamid Arabs) is the Nigerien name given to a number of Arab nomadic tribes people living in eastern Niger, mostly in the Diffa Region.
In 2006, approximately 150,000[1][2][3] accounting for less than 1.5% of the Niger's population, the Diffa Arabs are said to be the westernmost dispersion of Arabic-speaking Sudanese nomads, primarily drawn from the Mahamid subclan of the Rizeigat of Sudan and Chad.
