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.

Line 13 was extended in 1976 to reach the northern end of Line 14, which was then absorbed into it. The number 14 was eventually reused for a new line in 1998.
The Île-de-France tramways is a network of modern tram lines in the Île-de-France region of France. Fourteen lines are currently operational, with extensions and additional lines in both construction and planning stages. Although the system mainly runs in the suburban regions of Paris, lines T3a and T3b run entirely within Paris city limits, while lines T2 and T9 start their routes within Paris' borders. While lines operate independently of each other and are generally unconnected, some connections do exist: between lines T2 and T3a, T3a and T3b, T1 and T5, T1 and T8, T8 and T11 Express, T3a and T9 and T6 and T10. However, the final design of the entire planned tram network is fairly integrated.

It has been managed by Tisséo Voyageurs, under the authority of Tisséo Collectivités, also named the Syndicat Mixte des Transports en Commun, an authority established by various local government bodies, since 2003.

Île-de-France tramway lines 3a and 3b are the first modern tramway in Paris proper since the 1937 closure of the previous comparable system. They are operated by the RATP and divided into two sections called T3a and T3b. The line is also known as the Tramway des Maréchaux because it follows the Boulevards of the Marshals, a series of boulevards that encircle Paris along the route of the former Thiers Wall. The boulevards are, with three exceptions, named for Napoleon's First Empire marshals (maréchaux); they were transformed by redevelopment works carried out during the two and a half year construction of the line, which opened on 16 December 2006 under the designation T3.
Paris Métro Line 15 is one of four new lines of Grand Paris Express, a major expansion project of the Paris Métro.

The southern section of the line is planned to open in 2025, with the completed line planned to open in 2031.

In future, trains could be ordered for Line 1 and Line 6.
