Montparnasse — Bienvenüe is a station of the Paris Métro which is a transfer point between lines 4, 6, 12 and 13. It is the fourth busiest station on the metro system in Montparnasse at the intersection of the 6th, 14th and 15th arrondissements. 

It provides access to the Tour Montparnasse and the Gare Montparnasse. Fare Zone: 1.

On 24 April 1906 the station opened as Montparnasse station in the Avenue du Maine at the southern end of the old Gare Montparnasse. On 11 March 1910 the Montparnasse station was renamed Avenue du Maine and on 30 June 1933 it was renamed Bienvenüe in honour of the principal engineer of the Paris Métro, Fulgence Bienvenüe (accounting for the unusual diaeresis in the station's name).

The southern part of the station in the Avenue du Maine was the location of the Barrière du Maine, 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.
