The Waning of the Middle Ages is the best-known work by the Dutch historian Johan Huizinga.

Its subtitle is: "A study of the forms of life, thought and art in France and the Netherlands in the fourteenth and fifteenth centuries".

In the book, Huizinga presents the idea that the exaggerated formality and romanticism of late medieval court society was a defense mechanism against the constantly increasing violence and brutality of general society. He saw the period as one of pessimism, cultural exhaustion, and nostalgia, rather than of rebirth and optimism.
