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.

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 main settlements in Mundariland are Terekeka, Gemeiza, Mangalla, Muni, Tombek, Tindilo, Tali, Rego, Tijor, Rijong, Koweri, and Nyori.

In common with other Nilotic tribes in Sudan, the Mundari practice ritual scarification as a rite of passage into adulthood for young men.

The typical Mundari scar pattern consists of two sets of three parallel lines, each on either side of the forehead, extending in a downward slope and unconnected in the middle.
