Île-de-France tramway Line 5

Île-de-France tramway Line 5 (usually called simply T5) is part of the modern tram network of the Île-de-France region of France. Line T5 connects Garges–Sarcelles station and the centre of Saint-Denis (Marché de Saint-Denis) and , in the northern suburbs of Paris. Line T5 was Île-de-France's first rubber-tyred tramway line. The line has a length of 6.6 km (4.1 mi) and 16 stations. It opened to the public on 29 July 2013.

First envisioned during the 1990s as a means of providing better public transportation through Paris's northern suburbs, particularly the expanding districts of Pierrefitte-sur-Seine and Lochères in Sarcelles, actual planning activity for the line started during 1999. During February 2005, the defined Line 5 project was publicly announced by the Syndicat des Transports (STIF). Transit operator RATP was appointed as the principal contractor for performing the construction of the new line. During the latter part of 2009, work commenced upon Line 5's civil engineering works; construction commenced upon the track infrastructure and stations almost one year later.

The line is operated by the RATP Group under contract with Île-de-France Mobilités.
