The South Bauchi languages (also called the B.3 West Chadic or Barawa languages) are a branch of West Chadic languages that are spoken in Bauchi State and Plateau State, Nigeria. An extensive lexical survey of the South Bauchi languages had been carried out by Kiyoshi Shimizu from 1974 to 1975. Another early survey was that of Gowers (1907), which included 42 languages of Bauchi.
