Cheikh Anta Diop (29 December 1923 – 7 February 1986) was a Senegalese historian, anthropologist, physicist, and politician who studied the human race's origins and pre-colonial African culture. Though Diop is sometimes referred to as an Afrocentrist, he predates the concept and thus was not himself an Afrocentric scholar. However, Diopian thought, as it is called, is paradigmatic to Afrocentricity. His work was greatly controversial and throughout his career, Diop argued that there was a shared cultural continuity across African peoples that was more important than the varied development of different ethnic groups shown by differences among languages and cultures over time.

Diop's work has posed important questions about the cultural bias inherent in scientific research. Cheikh Anta Diop University (formerly known as the University of Dakar), in Dakar, Senegal, is named after him.

Some Diop works have been criticized as revisionist and pseudohistorical.
