Charles de Gaulle–Étoile station is a station on Line 1, Line 2 and Line 6 of the Paris Métro, as well as on Île-de-France's commuter rail RER A. It lies on the border of the 8th, 16th and 17th arrondissements of Paris. Originally called simply Étoile, after its location at Place de l'Étoile, it took on the additional name of President Charles de Gaulle in 1970.

La Défense station is a station of the Transilien suburban rail lines, RER commuter rail network, Paris Métro, as well as a stop of the Île-de-France tram network. In the future, Paris Metro Line 15 of Grand Paris Express will pass through here, making it a huge railway hub. It is underneath the Grande Arche building in La Défense, the business district just west of Paris. The station is the western terminus of Métro Line 1 and connects the RER A line to the Métro Line 1 station La Défense–Grande Arche since 1992, the Line 2 tramway since 1994 and SNCF (Transilien) train station. It is also attached to a major shopping centre. There are over 25 million entries and exits each year. A temporary special SNCF service began in April 1959 to serve the newly-built Centre of New Industries and Technologies (CNIT); the RER entered service on 19 January 1970.
