The Istanbul Metro is a rapid transit railway network that serves the city of Istanbul, Turkey. Apart from the M11 line, which is operated by TCDD Taşımacılık, the system is operated by Metro Istanbul, a public enterprise controlled by the Istanbul Metropolitan Municipality. The oldest section of the metro is the M1 line, which opened in 1989. As of March 2024, the system now includes 158 stations in service, with 36 more under construction. Istanbul is the city with the 22nd longest metro line in the world and the 4th in Europe.

Rapid transit or mass rapid transit (MRT), also known as 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.
The London Underground is the world's first and oldest rapid transit system.
The New York City Subway is the world's largest single-operator rapid transit system by number of metro stations, at 472.
