The Nuer language is a Nilo-Saharan language of the Western Nilotic group. It is spoken by the Nuer people of South Sudan and in western Ethiopia. Nuer is one of eastern and central Africa's most widely spoken languages. The Nuer nation is one of the largest in South Sudan.

Nuer language has a Latin-based alphabet. There are also several dialects of Nuer, although all have one written standard. For example, while final /k/ is pronounced in the Jikany dialect, this sound is dropped in other dialects despite being indicated in Nuer orthography.

There are different dialects spoken by Nuer groups living in various locations in South Sudan. Some of the Nuer people live in Western Ethiopia. They are called Gajaak, Gajiok, and Lou. The Nuer of the Nasir region are called Gajiok, and those in Waat are called Lou. There are also Gaweer and Jikueichieng.
