The national flag of France (known in French as drapeau tricolore, drapeau français, and in military parlance, les couleurs) is a tricolour featuring three vertical bands coloured royal blue (hoist side), white, and red. It is known to English speakers as the French Tricolour or simply the Tricolour.

The royal government used many flags, the best known being a blue shield and yellow fleur-de-lis on a white background, or state flag. Early in the French Revolution, the Paris militia, which played a prominent role in the storming of the Bastille, wore a cockade of blue and red, the city's traditional colours. According to Lafayette, white, the "ancient French colour", was added to the militia cockade to create a tricolour, or national, cockade. This cockade became part of the uniform of the National Guard, which succeeded the militia and was commanded by Lafayette. The colours and design of the cockade are the basis of the Tricolour flag, adopted in 1790. A modified design by Jacques-Louis David was adopted in 1794. A solid white flag was used during the Bourbon restoration in 1815–30, but the tricolour has been used since.

France (English ⁱ/ˈfræns/ FRANSS or /ˈfrɑːns/ FRAHNSS; French: [fʁɑ̃s] ( listen)), officially the French Republic (French: République française [ʁepyblik fʁɑ̃sɛz]), is a unitary semi-presidential republic in Western Europe with several overseas territories and islands located on other continents and in the Indian, Pacific, and Atlantic oceans. Metropolitan France extends from the Mediterranean Sea to the English Channel and the North Sea, and from the Rhine to the Atlantic Ocean. It is often referred to as l’Hexagone ("The Hexagon") because of the geometric shape of its territory. It is the largest western European country and it possesses the second-largest exclusive economic zone in the world, covering 11,035,000 km² (4,260,000 sq mi), just behind that of the United States (11,351,000 km² / 4,383,000 sq mi).

Over the past 500 years, France has been a major power with strong cultural, economic, military and political influence in Europe and around the world. During the 17th and 18th centuries, France colonised great parts of North America and Southeast Asia; during the 19th and early 20th centuries, France built the second largest colonial empire of the time, including large portions of North, West and Central Africa, Southeast Asia, and many Caribbean and Pacific Islands.
