The Pojulu (or Pajulu)is a tribe of the savanna lands in the White Nile Valley, in the Equatoria region of South Sudan. They are Nilotic people and part of the Karo people — which also includes Bari, Mundari, Kakwa, Kuku, Nyangwara, and [[The Karo Tribes Of Omo Valley in Ethiopia such as the Banna, Hamer, Mursi , Kara, Dassanech, Arbore, Nyangatom known as the Omo Karo peoples.
The Pojulu differentiate into smaller clans of Nyori, Morsak, Wonduruba, Goduck, Lobora, Moje, Mulusuk, Pirisa, Malari, Mankaro, Sadim, Jomi, Nyigo, Komojok, Limbe, Mundu, Jebele, Maranga, Donni, Gokoni, Borri, Moyita, Gojang, Liggi, Soka, Yondoru, Mijibura, Wande and many more.
The majority of the Pojulu population are located in Lainya county Central Equatoria state, including Mukaya Payam. The Pojulu are also found in Juba and Yei county. Pojulu people also occupy the area from Lainya to Kagwada and Mukaya. The centre of Pojulu will be Kenyi Payam from Mundu 20 miles, Mukaya 18 miles, Wonduruba 21 miles, Bereka 15 miles, Lainya 9 miles and from Kagwada 22 miles.
The name Pojulu is derived from several sources. The Pojulu language can be differentiated from all the other Bari speakers from the way they pronounce words, for example how other Bari speakers say their greetings or how each group socialize — such as along the roads from Juba up to Lainya and from Lainya to Bereka and Wonduruba.
The environment in Central Equatoria is typically tropical. There can be arid periods with less rain. The neighbouring tribes are Bari to the east, Nyangwara to the north, Kakwa to the south, Mundu to the west, and Avukaya to the northwest.
The Pojulu people speak the Kutuk na Pojulu language, as other Karo people, but with particular dialectic variation which highlights the difference between the Pojulu among the Karo. This Bari language has some distinct variations linked to people's daily activities and traditions that have evolved over time from their experiences.
There is little knowledge about the origin of the Pojulu as a people, and their relation to the Bari and other Bari-speaking ethnic groups.
