The Ubangian languages form a fairly close-knit language family of some seventy languages centered on the Central African Republic. They are the predominant languages of the CAR, spoken by 2–3 million people, and include the national language, Sango. They are generally included in the Niger–Congo family, though this has not been demonstrated.
External classification 
Greenberg (1963) classified the then-little-known Ubangian languages as Niger–Congo and placed them within the Adamawa languages as "Eastern Adamawa". They were soon removed to a separate branch of Niger–Congo, for example within Blench's Savanna languages. However, this has become increasingly uncertain, and Dimmendaal (2008) states that, based on the lack of convincing evidence for a Niger–Congo classification ever being produced, Ubangian "probably constitutes an independent language family that cannot or can no longer be shown to be related to Niger–Congo (or any other family)." Blench (2012) notes that Dimmendaal presents no evidence, and continues to include Ubangian within Niger–Congo.
Internal classification 
Boyd and Moñino (2010) removed the Gbaya and Zande languages. The half dozen remaining branches are coherent, but their interrelationships are not straightforward. Williamson & Blench (2000) propose the following arrangement:
In addition there is the Ngombe language, whose placement is uncertain due to a paucity of data.
Ethnologue 16 agrees with Williamson & Blench on the Sere–Mba node.
Note: The ambiguous name Ngbaka is used for various languages in the area. Generally, singular Ngbaka language refers to one of the main Gbaya languages, whereas plural Ngbaka languages refers to a branch of Ubangian.
