Paris Métro Line 19 is a new line of the Paris Métro that is planned as an expansion of Grand Paris Express. Officially announced on 22 November 2023, it is planned to connect Nanterre–La Folie at the west of La Défense business district to Charles de Gaulle Airport and the new area to be developed at Triangle de Gonesse. It will serve the residential areas of the department of Val-d'Oise, notably Argenteuil and Garges-lès-Gonesse, in order to make them more accessible and accelerate their urban renewal. According to the first studies, the line is expected to be opened by 2040.
