The Madrid Metro is a rapid transit system serving the city of Madrid, capital of Spain. The system is the 14th longest rapid transit system in the world, with a total length of 293 km (182 mi). Its growth between 1995 and 2007 put it among the fastest-growing networks in the world at the time. However, the European debt crisis greatly slowed expansion plans, with many projects being postponed and canceled. Unlike normal Spanish road and rail traffic, which drive on the right, Madrid Metro trains use left-hand running on all lines because traffic in Madrid drove on the left until 1924, five years after the system started operating.

Rapid transit or mass rapid transit (MRT), also known as heavy rail or metro, is a type of high-capacity public transport that is generally built in urban areas. A rapid transit system that primarily or traditionally runs below the surface may be called a subway, tube, or underground. Unlike buses or trams, rapid transit systems are railways, usually electric, that operate on an exclusive right-of-way, which cannot be accessed by pedestrians or other vehicles. They are often grade-separated in tunnels or on elevated railways.

Road, rail and air links are vital to maintain the economic position of Madrid as a leading centre of employment, enterprise, trade and tourism, providing effective connections with not only other parts of the region, but also the rest of Spain and Europe as a whole. Three quarters of a million people commute into the city to work, and these and other local travellers have available a high-capacity metropolitan road network and a well-used public transport system based on the Metro, the Cercanías local railways, and a dense network of bus routes.
