Noctilien is the night bus service in Paris and its agglomeration. It is managed by the Île-de-France Mobilités (formerly the STIF), the Île-de-France regional public transit authority, and operated by RATP (with 32 lines) and Transilien SNCF (with 16 lines).

It replaced the previous Noctambus service on the night of 20/21 September 2005, providing for a larger number of lines than before and claiming to be better adapted to night-time transport needs.
In place of the previous hub-and-spoke scheme where all buses terminated at and departed from the heart of Paris: Châtelet  , Noctilien's new service includes buses operating between banlieues (communes surrounding Paris proper) as well as outbound lines running from Paris' four main railway stations: Gare de l'Est, Gare de Lyon, Gare Montparnasse and Gare Saint-Lazare. In addition, these four stations are also connected to each other by a regular night bus service.

In addition, these four stations are also connected to each other by a regular night bus service.

All in all, Noctilien operates 48 bus lines, from the end of the rail network and day bus service (around 00:30) until their resumption early in the morning (around 05:30), over the whole of Paris and the Île-de-France region.
It is made up of:
- 2 circular lines: N01 & N02 running between Paris' major train stations ;
- 6 transversal lines: from N11 to N16 running between different suburbs of Paris via its center at Châtelet ;
- 21 radial lines (the other 2 digits lines, except N71) running between major Paris stations and more or less its near suburbs ;
- 2 radial long distance lines: N122 & N153 (subcontracted by the RATP) running between Paris and its remote suburbs ;
- 15 radial long distance lines (the other 3 digits lines, except N135) running between Paris and its remote suburbs (with often a partly motorway route) and managed by the Transilien SNCF ;
- 2 ring lines in the suburbs: N71 by RATP & N135 by Transilien SNCF.
Like Transilien, the name "Noctilien" is formed by analogy with "Francilien" — the French demonym for residents of Île-de-France.
