The Nilotic people are people indigenous to South Sudan and the Nile Valley who speak Nilotic languages. They inhabit South Sudan and the Gambela Region of Ethiopia, while also being a large minority in Kenya, Uganda, the northern area of Democratic Republic of the Congo, and Tanzania. The Nilotic people consist of the Dinka, the Nuer, the Shilluk, the Luo peoples, the Alur, the Anuak, the Ateker peoples, the Kalenjin people and the Karamojong people also known as the Karamojong or Karimojong, Ngasa people, Datooga, Samburu, and the Maa-speaking peoples. Each of the ethnic groups mentioned have distinct languages, ethnic origins, and migration history, so the grouping under the name Nilotic or Nilotes is anthropologically contentious.
The Nilotes constitute the majority of the population in South Sudan while constituting a substantial minority in the countries of Uganda, Tanzania and Kenya. They make up a notable part of the population of North eastern Democratic Republic of Congo as well. Nilotic people are believed to number 50 million in the 21st century.
