Chaussée d'Antin–La Fayette (French pronunciation: [ʃose dɑ̃tɛ̃ la fajɛt]) is a station on Line 7 and Line 9 of the Paris Métro. The station was opened on 5 November 1910 with the opening of the first section of the line from Opéra to Porte de la Villette. The line 9 platforms opened on 3 June 1923 with the extension of the line from Saint-Augustin.

The station was originally named Chaussée d'Antin after the street of Chaussée d'Antin—which was named after himself by Louis Antoine de Pardaillan de Gondrin, first Duke of Antin (1665–1736) in 1712. In 1989 La Fayette was added referring to famous shopping street of Rue La Fayette, named after Gilbert du Motier, marquis de Lafayette.

The area was once a marsh to the north of the old Porte Gaillon (a gate in the extension of Paris's walls, built under Louis XIII). Louis XV's frequent visits to Paris led to the building in the area of several splendid residences, including a mansion built by Louis Antoine de Pardaillan de Gondrin, Duc d'Antin, son of Marquise de Montespan (later a long-time mistress to Louis XIV of France) and the King's Superintendent of Building, Louis Henri Pardaillan de Gondrin, Marquis de Montespan.

The main Galeries Lafayette department store in the Boulevard Haussmann is nearby.

In April 2012, a driver mistakenly drove his car into a station entrance, thinking it was an underground car park.

The station has six accesses divided into seven metro entrances:

• access 1 - Grands magasins - Galeries Lafayette, consisting of a fixed staircase decorated with a Dervaux candelabra, leading to the corner of Boulevard Haussmann and Rue de la Chaussée-d'Antin, to the right of the Galeries Lafayette Haussmann;

The platforms of the two lines, with a conventional length of seventy-five metres, are of standard configuration. There are two per stopping point, they are separated by the metro tracks located in the centre and the vault is elliptical. Each of the vaults is decorated with a painted sheet metal fresco, created by the French painter Jean-Paul Chambas in 1989, on the bicentenary of the French Revolution.

On line 7, this station is completed with an Andreu-Motte style decoration with two blue light canopies with the particularity of being topped with an additional lighting device to highlight the fresco, as well as benches covered with flat blue tiles and equipped with Motte seats of the same colour. Before 2020, the barriers surrounding the stair shafts on the platform towards La Courneuve - 8 Mai 1945 were also painted blue to harmonize with the decoration while respecting its colorimetric uniformity. These fittings are themselves combined with the flat white ceramic tiles that cover the walls and tunnel exits. The advertising frames are metal, and the name of the station is inscribed in Parisine font on enamelled plaques. The station is however distinguished by the lower part of the platform walls towards La Courneuve, which is vertical and not elliptical for most of its length, due to the presence of the numerous stair shafts. The name plates are thus arranged in a protruding manner on the curvature at the base of the vault.

On line 9, the station is accompanied by lighter Mott style fittings. The platforms have benches covered with flat brown tiles and topped with blue Motte seats (which replace white seats of the same model). There are no light canopies as is usual in stations of this style, the platforms only having indirect lighting provided by the lights hidden on the sides of the fresco, previously illuminated by projectors. As on line 7, the white ceramic tiles are flat and cover the walls and tunnel exits. The advertising frames are metal and the name of the station, written with the Parisine font, appeared on backlit boxes until July 2022, but have since been replaced by classic enamelled plaques.

The station is served by lines 32, 45 and 68 (for the latter, in the direction of Châtillon - Montrouge only) of the RATP Bus Network.
