The music of the Cameroon includes diverse traditional and modern musical genres. The best-known contemporary genre is makossa, a popular style that has gained fans across Africa, and its related dance craze bikutsi.

Traditional music The ethnicities of Cameroon include an estimated 250 distinct ethnic groups in five regional-cultural divisions.
