Val de Fontenay station is a Réseau Express Régional station in the Paris suburb Fontenay-sous-Bois. It is on the Paris-Est–Mulhouse-Ville railway and provides an interchange between the RER lines A and E.

The station is named for a neighborhood of Fontenay-sous-Bois. It is served by line A (branch A4) and line E (branch E4).

As of 2019, the estimated annual attendance was 14,295,323 passengers according the RATP Group and 17,693,555 passengers according the SNCF.

This attendance makes this station the second busiest station in the Val-de-Marne department.

On the A line, Val de Fontenay is the first station on the branch A4, leading to Marne-la-Vallée–Chessy and is also the busiest in terms of trains. Val de Fontenay (like Noisy-le-Grand-Mont d'Est) is served by every train running on this branch, unlike others which are skipped at certain times of day (Bry-sur-Marne and Lognes).

The station is served in each direction by:

• 12–18 trains on peak travel times.
• 9 trains per hour on off-peak hours.
• 6 trains per hour on week-ends.
• 4 trains per hour in the late evening.

Starting 4 February 2008, RATP changed the number of trains running on the RER A. In off-peak hours, there are now 12 trains per hour instead of 6. Of those 12 trains going to Marne-la-Vallée, 6 are direct between Val de Fontenay and Noisy-le-Grand (the stations of Neuilly-Plaisance and Bry-sur-Marne are skipped). This allows a passenger to save 2 minutes between Val de Fontenay and Noisy-le-Grand, as the trip drops from 7 minutes to 5 minutes without the two stops.

Since 30 August 1999, Val de Fontenay has also been served by the RER E. This is the branch E4, going between Haussmann–Saint-Lazare and Tournan. Train service on the E line consists of 6 trains per hour during the week in both directions. Towards Tournan, there are 4 trains per hour to Villiers-sur-Marne–Le Plessis-Trévise and 2 trains per hour to Tournan. Towards Haussmann–Saint-Lazare, trains coming from Villiers-sur-Marne stop at all stations, while trains coming from Tournan stop only at Noisy-le-Sec, Pantin, Rosa Parks and Magenta. In the evening, there are 4 trains per hour, alternating between Villiers-sur-Marne and Tournan and stopping at all stations.

The station is served by several buses:

• RATP Bus:  116 ,  118 ,  122 ,  124 ,  301 ,  524 
• Les Autobus du Fort: 702
• Noctilien: N34, N71, N142
