The Hippodrome de Longchamp, commonly referred to as "Longchamp," is a 57 hectare horse-racing facility located on the Route des Tribunes in the Bois de Boulogne at Paris, France. Built on the banks of the Seine River, it is used for flat racing and is noted for its variety of interlaced tracks and a famous hill that provides a real challenge to competing thoroughbreds. Longchamp has 17 hectares that are used for several racetracks varying from 1,000 to 4,000 meters in length with 46 different starting posts.

The highlight of racing at the facility is the annual Prix de l'Arc de Triomphe. Held on the first weekend in October, the prestigious event attracts the best horses from around the world.

A number of prominent artists have painted horse racing scenes at Longchamp including the one seen here painted by Édouard Manet in 1867 and another four years later by Edgar Degas titled Race Horses at Longchamp.
