Iéna (French pronunciation: [jena]) is a station on Line 9 of the Paris Métro, named after the Avenue d'Iéna.

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

It is the nearest station to the Guimet Museum (Asian art) and the Palais de Tokyo (contemporary art museum), as well as the Embassy of Mexico, the International Chamber of Commerce, and the Pont d'Iéna ("Jena Bridge").

The station has three entrances made up of fixed stairs, which have an original balustrade, matching the railings of the Musée national des Arts asiatiques - Guimet located north of the Place d'Iéna : Jena is a standard station.

The lighting canopies are white and rounded in the Gaudin style of the Renouveau du métro renovations of the 2000s, and the bevelled white ceramic tiles cover the right legs, the vault and the tunnel exits.
