The forest of Fontainebleau is a mixed deciduous forest lying sixty kilometres southeast of Paris, France. It is located primarily in the arrondissement of Fontainebleau in the southwestern part of the department of Seine-et-Marne. Most of it also lies in the canton of Fontainebleau, although parts of it extend into adjoining cantons, and even as far west as the town of Milly-la-Forêt in the neighboring department, Essonne. Several communes lie within the forest, notably the towns of Fontainebleau and Avon. The forest has an area of 280 km².
