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,
Rijong, South Sudan,
