Mairie d'Issy (French pronunciation: [mɛʁi disi]) is the southern terminus of line 12 of the Paris Métro in the commune of Issy-les-Moulineaux.

Shops located on the avenue Victor Cresson and avenue de la République are served by the station.

The station opened on 24 March 1934 as part of the extension of the line from Porte de Versailles.

It is one of only two stations on the line to be decorated in the style of the Compagnie du chemin de fer métropolitain de Paris (CMP) instead of the Nord-Sud style used on the other stations, with the other station being Corentin Celton.

The station is also served by lines 123, 169, 190, 290, 323, and TUVIM of the RATP bus network, and at night, by line N13 of the Noctilien bus network.
