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.

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.

[1] Diop did not have an early interest in acting, but rather planned to pursue a career in textiles, specifically as a parachutist.

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 appeared in the 2019 short documentary by Johanna Makabi Our Memory (Notre mémoire), played in the 2024 French Film Festival.
