The 1st constituency of Val-de-Marne lies in the centre of the department to the south west of Paris.

It includes part of Saint-Maur-des-Fossés and the north of Créteil both of which form part of Paris's suburbs.

The constituency is part of the more conservative eastern half of the department.

The result of the 2012 election was overturned by the Constitutional Council leading to a by-election in which the incumbent Henri Plagnol was defeated by Sylvain Berrios standing as a dissident UMP candidate.
