The Grandes Heures of Anne of Brittany (Les Grandes Heures d'Anne de Bretagne in French) is a book of hours, commissioned by Anne of Brittany, Queen of France to two kings in succession, and illuminated in Tours or perhaps Paris by Jean Bourdichon between 1503 and 1508. It has been described by John Harthan as "one of the most magnificent Books of Hours ever made", and is now in the Bibliothèque nationale de France as Ms lat. 9474. It has 49 full-page miniatures in a Renaissance style, and more than 300 pages have large borders illustrated with a careful depiction of, usually, a single species of plant.
