Paris Métro Line 7 is one of sixteen lines of the Paris Métro system. Crossing the capital from its north-eastern to south-eastern sections via a moderately curved path, it links La Courneuve – 8 mai 1945 in the north with Mairie d'Ivry and Villejuif – Louis Aragon in the south, while passing through important parts of central Paris.

The Paris Métro, operated by the Régie autonome des transports parisiens (RATP), is a rapid transit system in the Paris metropolitan area, France. A symbol of the city, it is known for its density within the capital's territorial limits, uniform architecture and unique historical entrances influenced by Art Nouveau. The system is 226.9 kilometres (141.0 mi) long, mostly underground. It has 308 stations of which 64 have transfers between lines. There are 16 lines, numbered 1 to 14, with two lines, Line 3bis and Line 7bis, named because they used to be part of Line 3 and Line 7, respectively. Line 1, Line 4 and Line 14 are automated. Lines are identified on maps by number and colour, with the direction of travel indicated by the terminus.
