Mario Prassinos (1916–1985) was a French modernist painter, printmaker, illustrator, stage designer and writer of Greek-Italian descent. His first exhibition took place in 1938 at the Galerie Billiet-Pierre Vorms in Paris. That same year he married Yolande Borelly. His daughter Catherine Prassinos was born in 1946. Prassinos' work is found in major art museums in Europe and North America, including the Stedelijk Museum, Amsterdam; Musée National d'Art Moderne, Paris; Kunsthalle Bremen, Germany; Victoria and Albert Museum, London; Museum of Modern Art, New York; Metropolitan Museum of Art, New York; Art Institute of Chicago, and others. Prassinos died at his home in Eygalières, France on 23 October 1985. After his death, a donation of 800 of the artist's works was made to the French state. The "Donation Mario Prassinos" collection is housed in the Chapel of Notre-Dame de Pitié (also called Notre-Dame des Sept Douleurs) in Saint Remy de Provence, France.
