Le Mans (/lə ˈmɒ̃/, French: [lə mɑ̃] ) is a city in Northwestern France on the Sarthe River where it meets the Huisne. Traditionally the capital of the province of Maine, it is now the capital of the Sarthe department and the seat of the Roman Catholic diocese of Le Mans. Le Mans is a part of the Pays de la Loire region.

Its inhabitants are called Manceaux (male) and Mancelles (female). Since 1923, the city has hosted the 24 Hours of Le Mans, the world's oldest active endurance sports car race. The event is among the most attended and prestigious motor sports events in the world.

First mentioned by Claudius Ptolemy, the Roman city Vindinium was the capital of the Aulerci, a sub tribe of the Aedui. Le Mans is also known as Civitas Cenomanorum (City of the Cenomani), or Cenomanus. Their city, seized by the Romans in 47 BC, was within the ancient Roman province of Gallia Lugdunensis. A 3rd-century amphitheatre is still visible. The thermae were demolished during the crisis of the third century when workers were mobilized to build the city's defensive walls. The ancient wall around Le Mans is one of the most complete circuits of Gallo-Roman city walls to survive.

As the use of the French language replaced late Vulgar Latin in the area, Cenomanus, with dissimilation, became known as Celmins. Cel- was taken to be a form of the French word for "this" and "that", and was replaced by le, which means "the".

As the principal city of Maine, Le Mans was the stage for struggles in the eleventh century between the counts of Anjou and the dukes of Normandy. When the Normans had control of Maine, William the Conqueror successfully invaded England and established an occupation. In 1069 the citizens of Maine revolted and expelled the Normans, resulting in Hugh V being proclaimed count of Maine. Geoffrey V of Anjou married Matilda of England in the cathedral. Their son Henry II Plantagenet, king of England, was born in the town.

In the 13th century Le Mans came under the control of the French crown. It was subsequently invaded by England during the Hundred Years' War.

Industrialization took place in the 19th century which saw the development of railway and motor vehicle production as well as textiles and tobacco manufacture.

Wilbur Wright began official public demonstrations of the airplane he had developed with his younger brother Orville on 8 August 1908, at the Hunaudières horse racing track near Le Mans.

Soon after Le Mans was liberated by the U.S. 79th and 90th Infantry Divisions on 8 August 1944, engineers of the Ninth Air Force IX Engineering Command began construction of a combat Advanced Landing Ground outside of the town. The airfield was declared operational on 3 September and designated as "A-35". It was used by several American fighter and transport units until late November of that year in additional offensives across France; the airfield was closed.

The Gare du Mans is the main railway station of Le Mans. It takes 1 hour to reach Paris from Le Mans by TGV high speed train. There are also TGV connections to Lille, Marseille, Nantes, Rennes and Brest. Gare du Mans is also a hub for regional trains. Le Mans inaugurated a new light rail system on 17 November 2007.

The first French Grand Prix took place on a 64-mile (103 km) circuit based at Le Mans in 1906.

Since the 1920s, the city has been best known for its connection with motorsports. There are two official and separate racing tracks at Le Mans, though they share certain portions. The smaller is the Bugatti Circuit (named after Ettore Bugatti, founder of the car company bearing his name), a relatively short permanent circuit, which is used for racing throughout the year and regularly hosts the French motorcycle Grand Prix. The longer and more famous Circuit de la Sarthe is composed partly of public roads. These are closed to the public when the track is in use for racing. Since 1923, this route has been used for the famous 24 Hours of Le Mans sports car endurance race. Boutiques and shops are set up during the race, selling merchandise and promoting products for cars.

The "Le Mans start" was formerly used in the 24-hour race: drivers lined up across the track from their cars, ran across the track, jumped into their cars and started them to begin the race.

The 1955 Le Mans disaster was a large accident during the race that killed eighty-four spectators.

The city is home to Le Mans Sarthe Basket, 2006 Champion of the LNB Pro A, France's top professional basketball division.

The team plays its home games at the Antarès, which served as one of the host arenas of the FIBA EuroBasket 1999.
