The Nuer language is a Nilotic language spoken by the Nuer people, primarily in South Sudan and Ethiopia, with smaller communities in Sudan. It is part of the Nilo-Saharan language family. The Nuer people, who are pastoralists and engage in cattle herding, have a significant cultural and linguistic heritage tied to the Nuer language.

Nuer is characterised by its agglutinative nature, where affixes are added to a root word to convey various grammatical meanings. The language uses Latin-based orthography, and its script includes special characters to represent unique Nuer sounds. The Nuer language plays a crucial role in preserving the cultural traditions, oral histories, and social structures of the Nuer people. It is used in various domains of daily life, including communication within the community, religious ceremonies, and storytelling. Efforts are made to document and preserve the Nuer language, recognising its importance in maintaining the cultural identity and heritage of the Nuer people.
