Grand Paris Express is a group of new rapid transit lines to be built in the île-de-France region in France. The project comprises four new lines, plus the extension of existing lines 11 and 14. Originally, it was conceived that the new lines would be known by color (Red Line, Orange Line, Green Line, etc.). This changed in 2013 to continue the numbering convention that the RATP utilizes and will comprise new lines 15, 16, 17, and 18. They are planned to open in stages through 2023.

Since August 2013, the New Grand Paris steering committee has met each trimester. The first public inquiry, focused on the southern section from Pont de Sèvres to Noisy - Champs, was held from October to mid-November, 2013.

Works began in 2015, with the first section scheduled to open between Pont de Sèvres Métro station and Noisy – Champs RER A station around 2020. This line was first proposed in the Orbival project, then integrated into the Arc Express.

In order to ensure better commuter service to the Northeastern inner suburbs, a six-station, 5 kilometres (3.1 mi) extension eastbound from Mairie des Lilas to Rosny-sous-Bois is under consideration. The scheme has been proposed by local authorities, and adopted during the 2007 review of the Ile-de-France Transportation Plan. The line should be extended to Rosny – Bois-Perrier by 2021. In 2015 preliminary work started on the extension. It will provide new connections with the RER E and the extended tramway line 1, which will be linked more easily to the downtown and the commuter hub of Châtelet - Les Halles.
