The Istanbul Metro is a massive rapid transit railway network serving Istanbul, Turkey.

It serves as a vital artery for the city's movement. As of 2024, the system spans 243.3 kilometers of track. This makes it the 21st longest metro system in the world. It also ranks as the 4th longest system in Europe. The network includes 160 stations currently in service. Workers are also actively building 36 more stations.

The system is operated by Metro Istanbul, a public enterprise. This company is controlled by the Istanbul Metropolitan Municipality. One exception is the M11 line, which is operated by TCDD Taşımacılık.

The system's design must account for Istanbul's unique geography. The city is divided by the Bosporus, a deep strait of water.

Because of this water, the European and Asian networks do not connect directly. There are eleven lines in total. Eight lines are located on the European side of the Bosporus. These include the M1A, M1B, M2, M3, M6, M7, M9, and M11 lines. Three lines serve the Asian side. These are the M4, M5, and M8 lines. To cross between continents, passengers use the Marmaray commuter rail. This rail connects to the metro network in several specific locations.

Engineers used specific methods to ensure the system is safe and durable. They used the cut-and-cover method to build the network. This method helps the structures withstand significant seismic activity. The entire network is built to survive an earthquake of up to 9.0 on the Richter magnitude scale. Building the M2 line presented unique challenges for workers. During the drilling process, crews discovered many archaeological sites. These ancient historical sites slowed or stopped construction for many stations, particularly in the south.

This shows how modern transit must sometimes wait for history.

Istanbul has a very long history of underground rail. The Tünel is the oldest underground urban rail line in the city. It entered service on 17 January 1875. It is the world's second-oldest underground urban rail line. It was also the first underground urban rail line in continental Europe. Although it is a funicular, it paved the way for future plans. In 1912, a French engineer named L. Guerby proposed the first master plan. His plan, titled Avant Projet d'un Métropolitain à Constantinople, included 24 stations. Other planners like Henri Prost and Marc Langevin also proposed networks later. However, the modern mass transit system did not begin until 1989.

The M1 line was the first modern section to open. It began service on 3 September 1989. It was originally called "Hafif Metro," which means "light metro." This name came from its design. The M1 line uses shorter trainsets and shorter station platforms than a traditional metro.

The line was later extended to reach Atatürk Airport in 2002. The M2 line began construction on 11 September 1992. A major section of the M2 opened on 16 September 2000. This line connects Taksim to Hacıosman. It even includes a station on the Golden Horn Metro Bridge.

The Taksim-Yenikapı extension cost $593 million to complete.

Different lines have different technical capabilities and speeds. The M11 line is quite different from the others. It has a higher maximum speed of 120 km/h. It uses trains similar to Chinese metro type B trains.

Some lines are also fully automated. This means they operate without a driver. The M5 and M7 lines are examples of these automated systems. The M6 line is known as the "Mini-Metro." It is a light metro line with a single track between stations. Most lines operate from 06:00 AM to 12:00 AM. However, some lines provide 24-hour service on weekends and public holidays.

Daily travel on the metro is managed through a specific payment system. Passengers use the Istanbulkart, which is a universal contactless payment card. The standard flat fare is 40 TL. There are discounted rates for specific groups. Students pay 20.08 TL per ride. Teachers and senior residents pay 25.06 TL. The metro connects to many other transit types. This includes the Istanbul Tram, Metrobüs, and various cable cars. It also links to the F1, F2, F3, and F4 funicular lines. This creates a massive, interconnected web for the entire city.
