Philibert de l'Orme was a French architect and writer, and one of the great masters of French Renaissance architecture. His surname is also written De l'Orme, de L'Orme, or Delorme.

French Renaissance architecture is a style which was prominent between the late 15th and early 17th centuries in the Kingdom of France. It succeeded French Gothic architecture. The style was originally imported from Italy after the Hundred Years' War by the French kings Charles VII, Louis XI, Charles VIII, Louis XII and François I. Several notable royal châteaux in this style were built in the Loire Valley, notably the Château de Montsoreau, the Château de Langeais, the Château d'Amboise, the Château de Blois, the Château de Gaillon and the Château de Chambord, as well as, closer to Paris, the Château de Fontainebleau.
