Odéon (French: [ɔdeɔ̃] ⓘ) is a station on lines 4 and 10 of the Paris Métro.
The station was opened on 9 January 1910 as part of the connecting section of line 4 under the Seine between Châtelet and Raspail.
It served as its eastern terminus until its extension to Place d'Italie (now on line 7) on 15 February 1930.
The walls of the platform were clad in a metal casing to improve the general appearance of the station.
As part of the "Un métro + beau" programme by the RATP, the station's corridors, lighting, as well as platforms of line 4 were renovated on 7 October 2008, removing the metal cladding on the platforms of line 4.
