Letters from My Windmill (French: Les lettres de mon moulin) is a 1954 French comedy-drama film directed by Marcel Pagnol, starring Rellys, Robert Vattier, Fernand Sardou and Édouard Delmont. Set in the countryside of Provence, the film is based on three tales from Alphonse Daudet's 1869 short story collection Letters from My Windmill: "The Three Low Masses", "The Elixir of Father Gaucher" and "The Secret of Master Cornille". It premiered on 5 November 1954 and had 2,399,645 admissions in France.

In 1968 Pagnol made a television film based on another story from the same collection, Le curé de Cucugnan. Roger Crouzet was hired again and reprised his role as Daudet from Letters from My Windmill.
