Paris Métro Line 7bis is one of the sixteen subway lines currently open on the Paris Métro. It connects Louis Blanc, in the 10th arrondissement to Pré Saint-Gervais in the 19th arrondisement in the north-eastern part of the city. With a length of 3.1 kilometres (1.9 mi) and eight stations, the line is the second shortest on the Paris Métro, only longer than Line 3bis.
The line was opened in 1911, then operating as a branch of Line 7. However, due to a large difference in passenger numbers between this branch and the other Line 7 branch (then operating from Louis Blanc to the Porte de La Vilette station), the Pré-Saint-Gervais branch was separated from Line 7, forming the current Line 7bis.
Métro Line 7bis serves the Parc des Buttes Chaumont.
The only officially set project on Line 7bis is the replacement of the MF88 trains throughout 2026, with the brand new MF19 trains currently on tests on Line 10. The merger with Line 3bis, connected through an existing rail tunnel and allowing the opening of a closed station (), is being studied. Line 7bis would be extended one station west to have its terminus at . The proposed merger of the lines was postponed indefinitely in March 2013. In October 2013 it was rescheduled in principle for 2030. This project, however, requires to be set after the trains replacement as the Voie Navette is currently used for MF88 train maintenance, preventing its use for public transportation purposes. It also is blocked by the current use of Voie Navette and the merger Porte des Lilas station by RATP for movie shootings.
