Paris's 18th constituency

The 18th constituency of Paris (French: Dix-huitième circonscription de Paris) is a French legislative constituency in the Paris département (75). Like the other 576 French constituencies, it elects one MP using the two-round system. It is based in the north of the department. In the 2010 redistricting of French legislative constituencies, the 18th stayed covering the same area of Paris, with a small boundary change.

Before the 1986 redistricting of French legislative constituencies, the 18th constituency referred to a constituency in the South-West of the city.
