Françoise Marie Blanche Renet (Paris May 20, 1924 Paris - Versailles March 23, 1995) was a French organist. She studied with Marcel Dupré (organ), Maurice Duruflé (improvisation), and Nadia Boulanger (harmony). For 30 years she was associated with the great Cavaillé-Coll at Saint-Sulpice (Paris): in 1955, she was named by Dupré Assistant Organist, maintaining the same position also with Dupré's successor Jean-Jacques Grunenwald. She was also Interim Organist during the Dupré/Grunenwald and Grunenwald/Roth interregna (1971-1973 and 1982–1985, respectively).
From 1972 to 1990, Renet taught the organ class at the Marcel Dupré Conservatory in Meudon.
