The Mandari are a small ethnic group of South Sudan and one of the Nilotic peoples.
The group is composed of cattle-herders and agriculturalists and are part of Karo people which also includes Bari, Pojulu, Kakwa, Kuku and Nyangwara. Kutuk na Mundari is also the name of their language, which is in similar to Kutuk na Kuku, Kutuk na Kakwa, Kutuk na Pojulu, Kutuk na Bari, and Kutuk na Nyangwara.
The traditional Mundari tribal lands are located roughly 75 kilometers north of Juba, the capital of South Sudan, and are centered on the town of Terekeka in the state of Central Equatoria. They are bordered to the north by the Bor Dinka at Maliththoor, Anuet, and to the south by the Bari of Juba 12 km at the Ku'da River. Their lands are bounded on the east by the White Nile and extend west to Laka Ma'di in Western Equatoria state, an area roughly 100 by 75 kilometers in size.
The land, like much of South Sudan, is predominantly flat and marked by occasional isolated large hills. The low-lying land contains many rivers and lakes and is prone to flooding during the rainy season. The soil is predominantly clay-based, causing drainage and water retention problems, and provides a very fertile basis in support of cattle grazing.
The main settlements in Mundariland are Terekeka, Gemaiza, Muni, Tombe, Tindalo, Tali, Rego, Tijor, Rijong, South Sudan, Koweri, and Ku'da.
