The Grigny to Corbeil-Essonnes or Plateau d'Évry line is a double-track, standard-gauge railroad line ten kilometers long located in the French department of Essonne, in the Île-de-France region. It serves the various districts of the new town of Évry. It is the first new passenger line built by the Société nationale des chemins de fer français (SNCF) since its creation in 1938. It forms line no. 988,000 of the national rail network.

Opened in two stages in 1974 and 1975, the line runs in parallel to—but is longer and more winding than—the line from Villeneuve-Saint-Georges to Montargis via Corbeil, known as the “ligne de la vallée,” to which it is connected at both ends. It is one of the main southern branches of RER line D and carries only fairly heavy commuter traffic. Although theoretically equivalent to the historic route through the Seine Valley, traffic restrictions on certain types of engines limit their use by non-RER traffic to a few exceptional detours. There are no level crossings.
