The Paris Métro (French: Métro de Paris) is the rapid transit system in Paris. It is a symbol of the city, notable for its homogeneous architecture, influenced by Art Nouveau. It has 16 lines, mostly underground, and a total length of 213 km (133 mi). There are 298 stations. Since some are on more than one line, there are 382 stops.

Paris has the most closely spaced subway stations in the world, with 245 stations within the 41 square kilometres (16 sq mi) City of Paris. Lines are numbered 1 to 14, with two minor lines, 3bis and 7bis. The minor lines were originally part of lines 3 and 7 but became independent. "7bis" would be written 7A in English.

Lines are identified on maps by number and colour. Direction of travel is shown by the terminus station.

Paris is the second busiest metro system in Europe after Moscow. It carries 4.5 million passengers a day. It carried 1.365 billion in 2005. Châtelet-Les Halles is the world's largest underground station.
