The history of Senegal is commonly divided into a number of periods, encompassing the prehistoric era, the precolonial period, colonialism, and the contemporary era.

The earliest evidence of human life is found in the valley of the Falémé in the south-east.

The presence of man in the Lower Paleolithic is attested by the discovery of stone tools characteristic of Acheulean such as hand axes reported by Théodore Monod at the tip of Fann in the peninsula of Cap-Vert in 1938, or cleavers found in the south-east. There were also found stones shaped by the Levallois technique, characteristic of the Middle Paleolithic. Mousterian Industry is represented mainly by scrapers found in the peninsula of Cap-Vert, as well in the low and middle valleys of the Senegal and the Falémé. Some pieces are explicitly linked to hunting, like those found in Tiémassass, near M'Bour, a controversial site that some claim belongs to the Upper Paleolithic, while other argue in favor of the Neolithic.
