The Bissa (or Bisa (singular), Bisan, Bissanno (plural)) are a Mande ethnic group of south-central Burkina Faso, northeastern Ghana and the northernmost tip of Togo. Their language, Bissa, is a Mande language that is related to, but not the same as, a cluster of languages in the old Borgu Kingdom area of Northeast Benin and Northwest Nigeria, including Busa, Boko, and Kyenga. An alternate name for the Bissa is Busansi or Busanga which is used by the Mossi people.
Daniel McFarland's Historical Dictionary of Upper Volta refers to them as "intrusive Mande who settled the area along the White Volta below Tenkodogo by 1300. Some live across the border in modern northern Ghana and Togo. According to some traditions, Rialle, progenitor of the Nakomse line of Mossi rulers was Busansi."
