Porte Dauphine, Metro station in Paris

Porte Dauphine is the western terminus of Paris Métro Line 2, built under the Place du Maréchal-de-Lattre-de-Tassigny in the 16th arrondissement. Its two half-stations, one for arrivals and one for departures, are joined by a tight 30-metre-radius turning loop, the only fully preserved "racket" layout in the network. The vaults keep their original cream flat tiles, and the platforms carry no advertising.

Porte Dauphine opened on 12 December 1900 as the western terminus of the first section of line 2 Nord, which became simply line 2 on 17 October 1907. It is named after the gate in the Thiers wall, itself named for Marie-Antoinette's Belle Faisanderie. Its subtitle honours Marshal Jean de Lattre de Tassigny (1889-1952), though it does not appear on maps.

The station's name comes from the Porte Dauphine, a gate of the Thiers wall located at the edge of Marie-Antoinette's Belle Faisanderie when she was dauphine. Its subtitle, Maréchal de Lattre de Tassigny, honours the French general (1889–1952) buried under the square above; it does not appear on maps. The cream flat tiles are an experimental decoration from 1900.

The station lies under Place du Maréchal-de-Lattre-de-Tassigny, with four entrances along Avenue Foch and Boulevard Lannes. Access 3 on Boulevard de l'Amiral-Bruix has the original Guimard canopy; access 4 on Avenue Hubert-Germain is exit-only. RER C at Avenue Foch is 170 metres away, and tram T3b has terminated here since April 2024.

The Art Nouveau entrance with its dragonfly canopy is the only original Guimard édicule still on its original site in Paris; a lighter reconstruction stands at Châtelet. The station also keeps its 1900 cream flat tiles, one of only two such survivors on the network.
