A Distant Mirror: The Calamitous 14th Century is a narrative history book by the American historian Barbara Tuchman.
The book's focus is the Crisis of the Late Middle Ages suffered by Europe in the 14th century. Drawing heavily on Froissart's Chronicles, Tuchman recounts the Hundred Years' War, the Black Plague, the Papal Schism, pillaging mercenaries, anti-Semitism, popular revolts including the Jacquerie in France, the liberation of Switzerland, the Battle of the Golden Spurs, and peasant uprisings. She also discusses the advance of the Islamic Ottoman Empire into Europe, ending in the disastrous Battle of Nicopolis. Yet Tuchman's scope is not limited to political and religious events. She begins with a discussion of the Little Ice Age, a change in climate that reduced the average temperature of Europe until the 18th century, and describes the lives of all social classes, from nobility and clergy to the peasantry.

Much of the narrative is woven around the life of the French nobleman Enguerrand de Coucy. Tuchman chose him as a central figure partly because he lived a relatively long life and could therefore stay in the story during most of the 14th century. (Coucy was born in 1340, seven years before the Black Death began in southern Italy. He died in 1397.) He was also close to much of the action, tied to both France and England. (Coucy was a French noble but he married Isabella, the eldest daughter of Edward III of England.)
