The Bainuk people (also called Banyuk, Banun, Banyun, Bainouk, Banyum, Bagnoun, Banhum, Banyung, Elomay, or Elunay) are an ethnic group that today lives primarily in Senegal as well as in parts of Gambia and Guinea-Bissau. The Bainuk are believed to have been the first inhabitants of the lower Casamance.
In the fifteenth century, there were at least five Bainuk states including Bichangor, Jase, Foni and Buguando. The Bainuk were also a major component of the population of Kasa.
In modern times the Bambe have often become absorbed into the Mande or Jola cultures.
