The Mexico City Metro (formally: Sistema de Transporte Colectivo Metro or STC Metro) is a rubber-tyred metro system that serves the metropolitan area of the Mexican Federal District (this includes some municipalities in the State of México).

In 2006 the system served an average of 1.417 billion passengers per year, the fifth highest ridership in the world.

The first Metro line relied on 16 stations, and was opened to the public in 1969. It has expanded since then in a series of fits and starts; it currently comprises eleven lines and 177 kilometres of passenger track. Trains feature rubber tires (also called pneumatic traction), instead of traditional steel wheels, decreasing noise and making the system more tolerable to Mexico City's unstable soils.

The Metro has 175 stations, 24 of which serve two or more lines. It has 106 underground stations (the deepest of which are 35 metres below street surface); 53 surface stations and 16 elevated stations. Eleven stations are located in the State of Mexico. This area where the stations are located is part of the metropolitan area of Mexico City, while the rest are within the limits of the suburbs with State of Mexico.

By the end of 2007, Mexican Federal District government announced the construction of the new metro line: Line 12. Line 12 will run towards the southeastern part of the city, with connections with Line 2, Line 3, Line 7 and Line 8.

In the connection with Line 8, a new station Axomulco Station will be built. This station will be for Line 8 and Line 12.
