This "quartier" of Paris got its name from the rue de la Chaussée-d'Antin in the 9th arrondissement of Paris. It runs north-northwest from the Boulevard des Italiens to the Église de la Sainte-Trinité. In the 17th century the chemin des Porcherons crossed a swampy piece of ground north of the porte Gaillon, a city gate in the wall built during the reign of Louis XIII, leading to the village of Les Porcherons. It is called a chaussée because the marshy ground required raised construction that ran along the top of a sort of dyke.
