Avenue Foch station (French: Gare de l'Avenue Foch) is a station in the Paris express suburban rail system, the RER. It is in the 16th arrondissement of Paris. It had previous been called Avenue du Bois de Boulogne as part of the Auteuil line, but was renamed following the change to the road itself. The station was once a "sunken" station, meaning that it was not covered.
