Béatrice Casadesus (born 1 January 1942) is a French painter and sculptor, and professor at the École nationale supérieure des Beaux-Arts in Paris, France.

From 1960 to 1966, she studied painting and sculpture with Henri-Georges Adam at the École des Beaux-Arts de Paris, and participated in the Roman theater group of the Sorbonne alongside Jean-Pierre Miquel, François Joxe [fr], and Jacques Lacarrière.

In 1964, she received the Prix de Rome for sculptors, and stayed in Italy, and with a grant from Fondation Marcel-Bleustein-Blanchet pour la vocation [fr], she began a collaboration with architects, including Antoine Stinco.

After the discovery of Georges Seurat, she abandoned sculpture for painting, and developed from 1980 and until 1989 the Tramaturgies inspired by Leonardo da Vinci, Michelangelo, and School of Fontainebleau.

From 1990 to 2000 she worked on fingerprints and explored the theme of the materiality of the paint on different paper substrates such as washi, tarlatan, and non-woven textiles.
