Rue du Bac (French pronunciation: [ʁy dy bak]) is a station on line 12 of the Paris Métro in the 7th arrondissement.

The station opened on 5 November 1910 as part of the original section of the Nord-Sud Company's line A between Porte de Versailles and Notre-Dame-de-Lorette.

On 24 February 2011, a cultural panel in memory of the poet and resistance fighter René Char (1907-1988) was placed on the platform towards Mairie d'Issy.

The station was chosen for the installation of the panel as a nearby public square, Place René-Char, was already named after him on the centenary of his birth in 2007.

The lower portion of the side walls are vertical instead of elliptical, as were the other stations constructed by the Nord-Sud company (today on lines 12 and 13).
