The book of hours of Joan of France is a 15th-century illuminated manuscript forming a book of hours, named after Joan of France, Duchess of Bourbon, who owned the book in the 15th century. After her death, it passed to Catherine of Armagnac, whose coat of arms was added to the book. After her death, the whereabouts of the book are unknown; it reappeared again in the late 19th century when it was bought by private collector Victor Martin Le Roy. It then passed to his son-in-law, art historian Jean-Joseph Marquet de Vasselot. It was again sold in 2011, and then bought by the Bibliothèque nationale de France, thanks to funding from private donors. It is classified as a national treasure of France. The rich decoration, including 28 full-page miniatures, was mostly made by the so-called Master of Jouvenel.
