group of some 120,000 people inhabiting a belt of hills covered by wooded savannas where Guinea, Sierra Leone, and Liberia meet; they speak a language of the Atlantic (Atlantic languages) branch of the Niger-Congo (Niger-Congo languages) family.

Rice, cultivated in marshes, is the staple of the Kisi diet; other foods include yams, groundnuts (peanuts), cotton, bananas, melons, and taro. Coffee and kola are grown for external trade. Kisi villages are built of round clay huts with conical roofs. They rarely contain more than 150 persons and are composed of several exogamous patrilineages. Each lineage is headed by its senior member, who serves as the priest of the ancestor cult and the intermediary between the living and the dead family members.

Kisi religion includes agricultural, ancestral, and other cults. Small steatite (stone) statuettes (kisi), made by former inhabitants of the area, are used to represent the ancestors, who provide the only means of communication with the creator god.
