Mbissine Thérèse Diop (born 1949) is a Senegalese actress best known for her starring role as Diouana in the 1966 Ousmane Sembène film Black Girl (La noire de...), which is often cited as one of the first feature films of African cinema to go on to international acclaim.^[1]

Diop was born in Dakar, Senegal to a Muslim father and a Catholic mother. The oldest in her family, Diop lived with her maternal grandfather until he died when she was two, at which time she returned to Dakar. Diop lived in Corsica when she was thirteen, where her hostess familiarised her with Josephine Baker.^[1]

Diop did not have an early interest in acting, but rather planned to pursue a career in textiles, specifically as a parachutist. The recommendation of a friend made Diop think more seriously about acting and the arts, and prompted Diop to reach out to Josephine Baker. After a correspondence, Baker invited Diop to visit her in France, but Diop had to decline due to cost. Diop frequented the Cine-Club in Dakar, where she was exposed to French and American films, and later enrolled at the Ecole des Arts de Dakar when she was sixteen, where she took night courses and studied under French actor Robert Fontaine (who later also starred in Black Girl). Diop worked as a seamstress during the day.
