Dupleix (French pronunciation: [dyplɛks]) is an elevated station on Line 6 of the Paris Métro, along the Boulevard de Grenelle in the 15th arrondissement. The track and station form an elevated viaduct in the centre of and above the Boulevard de Grenelle. There is an open street market under the station twice a week, on Wednesdays and Saturdays.
The station opened as part of the former Line 2 South on 24 April 1906, when it was extended from Passy to Place d'Italie. On 14 October 1907 Line 2 South was incorporated into Line 5. The station was then incorporated into line 6 on 12 October 1942. It is named after the nearby Place Dupleix, a square commemorating Joseph François Dupleix, marquis of Landrecies and Paris, an administrator and colonizer of India. The station was the location of the Barrière de Grenelle, a gate built for the collection of taxation as part of the Wall of the Farmers-General; the gate was built between 1784 and 1788 and demolished in the nineteenth century.
