Deauville (pronounced: [do.vil]) is a commune in the Calvados département in the Basse-Normandie region in northwestern France.

With its racecourse, harbour, international film festival, marinas, conference centre, villas, Grand Casino and sumptuous hotels, Deauville is regarded as the "queen of the Norman beaches" and one of the most prestigious seaside resorts in all of France. Closest seaside when coming from Paris, the city and the nearby region of the Côte Fleurie (Flowers Coast) has long been home to French high society's seaside houses and is often referred to as the Parisian riviera. Since the 19th century, the town of Deauville has been a fashionable holiday resort for the international upper class. Deauville is also a desired wealthy family resort. In France, it is known perhaps above all for its role in Proust's In Search of Lost Time.
