Dupleix is an elevated station on Line 6 of the Paris Métro in the 15th arrondissement. The track and station form an elevated viaduct in the centre of the Boulevard de Grenelle. It is named after the nearby Rue Dupleix and Place Dupleix, a square commemorating Joseph François Dupleix (1697–1763), marquis of Landrecies and Paris, an administrator and coloniser 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 before it was demolished in the 19th century.

Line 6 is one of the sixteen lines of the Paris Métro rapid transit system. Following a semi-circular route around the southern half of the city above boulevards built along the path of the former Fermiers généraux wall of 1784–1860, it runs between Charles de Gaulle–Étoile in the west and Nation in the east. A significant part of the route is on elevated tracks.
