The Kolkata Metro is a rapid transit system serving the city of Kolkata and the wider Kolkata Metropolitan Region in West Bengal, India. Opening in 1984, it was the first operational rapid transit system in India, beside being the second busiest and fourth-longest metro network in India. As of March 2024^[update], it has four operational lines: the 32.13 km (19.96 mi) Line 1 from Dakshineswar to Kavi Subhash, 14.1 km (8.8 mi) Line 2 from Salt Lake Sector V to Howrah Maidan (excluding the under construction section between Sealdah and Esplanade), 7.75 km (4.82 mi) Line 3 from Joka to Majerhat and 5.4 km (3.4 mi) Line 6 from Kavi Subhash to Hemanta Mukherjee for a total of 59.38 km (36.90 mi).^[3][4] Two other lines are in various phases of construction and planning. The system has a mix of underground, at-grade and elevated stations using both broad-gauge and standard-gauge tracks. Trains operate between 06:55 and 22:30 IST and the fares range from ₹5 to ₹50.

The Kolkata Metro was initially planned in the 1920s, but construction started in the 1970s. The first underground stretch, from Bhawanipore (now Netaji Bhawan) to Esplanade, opened in 1984. A truncated section of Line 2, or the East–West Corridor, from Salt Lake Sector V to Phoolbagan opened in 2020. Line 3, or the Joka-Esplanade Corridor (currently truncated in Majerhat), opened in 2022. It is the fourth-longest operational metro network in India after the Delhi Metro, Namma Metro and Hyderabad Metro.

Metro Railway, Kolkata and Kolkata Metro Rail Corporation are the owners and operator of the system. On 29 December 2010, Metro Railway, Kolkata, became the 17th zone of the Indian Railways, completely owned and funded by the Ministry of Railways. It is the only metro system in the country to be controlled by Indian Railways. There are around 300 daily train trips, carrying more than 700,000 passengers.
