Rennes (French pronunciation: [ʁɛn] ) is a station on line 12 of the Paris Métro in the 6th arrondissement.

Located in the 6th arrondissement, part of the Left Bank of the city, Rennes is one stations on line 12 that lie beneath Boulevard Raspail, in this case, at its intersection with rue de Rennes. It is from this street that it takes its name, which in turn is named after the city of Rennes.

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 27 March 1931, line A became line 12 when It was taken over by its competitor, the Compagnie du chemin de fer métropolitain de Paris (CMP), incorporating it into the Paris Métro.

On 2 September 1939, the station was closed as part of the government's plan that reduced service on the métro network as a cost-saving measure in light of the onset of World War II, with all but 85 stations closed. Most reopened after the war, although some of them, including Rennes, remained closed due to their light traffic, hence, becoming a ghost station. For a period of time while it was closed, it was used to experiment with advertising schemes which could be viewed from passing trains.

On 20 May 1968, after 29 years of closure, the station was finally reopened, albeit with limited operating hours as a cost saving measure. It was closed after 8pm from Monday to Saturday, and was closed all day on Sundays and public holidays. The walls of the station were coated with a white layer of paint due to the lack of maintenance causing the tiles on the walls to deteriorate.

In 2002, it was reported that the station had 4400 "incoming" commuters per day.

This arrangement lasted until 7 September 2004, when it was adjusted to the standard operating hours of most other stations at the local residents' request. This was due to changes in commuting patterns, where more commuters returned home later in the evening in addition to high traffic to Marché Raspail, a traditional market nearby, on Sundays. Only Liège on line 13 retained limited operating hours, until 4 December 2006.

As part of the "Un métro + beau" programme by the RATP, the station was renovated and modernised on 7 October 2008.

In 2019, the station was used by 1,181,641 passengers, making it the 287th busiest of the Métro network out of 302 stations.

In 2020, the station was used by 506,779 passengers amidst the COVID-19 pandemic, making it the 291st busiest of the Métro network out of 304 stations.

In 2021, the station was used by 861,334 passengers, making it the 287th busiest of the Métro network out of 304 stations.
