Alma–Marceau (French pronunciation: [alma maʁso]) is a station on Line 9 of the Paris Métro, named after the Pont de l'Alma (Alma Bridge) and the Avenue Marceau.

The station opened on 27 May 1923 with the extension of the line from Trocadéro to Saint-Augustin.

The Battle of Alma was a Franco-British victory against the Russians in the Crimean War in 1854. General François Séverin Marceau-Desgraviers (1769–1796) fought the Revolt in the Vendée during the French Revolution.

As was the case of a third of the stations in the network between 1974 and 1984, its platforms were modernised in the Andreu-Motte style, in this case in a shade of blue that was not renewed. As part of the RATP's Metro Renewal programme, the station's corridors were opened, after renovation, on 15 March 2002.

The station has three accesses equipped with Dervaux-type balustrades:

• Access 1 - Avenue Montaigne - Théâtre des Champs-Élysées, consisting of a fixed staircase decorated with two Dervaux lampposts (a rare case for the network which often uses only one signal per entrance), leading to the right of no. 7 Place de l'Alma, at the corner with Avenue Montaigne and Avenue George-V;
• Access 2 - Pont de l'Alma, Bateaux mouches; Musée du Quai Branly - Jacques-Chirac, also consisting of a fixed staircase with two Dervaux masts, facing No. 1 Place de l'Alma, at the corner with Avenue de New-York. It gives direct access to Diana Square;
• Access 3 - Avenue du Président-Wilson - Musée d'Art moderne, Palais de Tokyo, consisting of a fixed staircase doubled by an escalator going up and equipped with a Dervaux totem, located to the right of no. 4 in this avenue.

Alma - Marceau is a standard station. It has two platforms separated by the metro tracks and the vault is elliptical. The decoration is in the Andreu-Motte style with two blue light canopies, benches, tunnel exits, and most of the corridor openings treated in flat blue tiles and Motte seats of the same colour. These fittings are combined with the bevelled white ceramic tiles that cover the walls, the vault, and a corridor threshold on the platform towards Pont de Sèvres. The advertising frames are made of honey-coloured earthenware, and the name of the station is also in earthenware in the style of the original CMP. The station is distinguished, however, by the lower part of its walls, which is vertical and not elliptical, its immediate proximity to the river Seine requiring a reinforced construction resulting in a special profile.

It is one of the few platforms to still present the Andreu-Motte style in its entirety.

The station is connected to the Pont de l'Alma station (on line C of the RER), located on the other side of the Pont de l'Alma. This connection is shown on the RATP map of metro line 9, with a walking symbol. (remote connection).

In addition, it is served by lines 42, 63, 72, 80 and 92 of the RATP Bus Network.
