The Kolkata Metro (Bengali: কলকাতা মেট্রো) is a rapid transit system in West Bengal, India. It gives service to the city of Kolkata and the larger Kolkata Metropolitan Area. Opened in 1984, it is the first rapid transit system in India. It is also the second busiest and fourth-longest metro system in India. As of March 2024, it has four active lines: Line 1 (Blue Line), Line 2 (Green Line), Line 3 (Purple Line) and Line 6 (Orange Line).

Line 1 is 32.33-kilometre (20.09-mile) long. It runs from Dakshineswar to Kavi Subhash. Line 2 is 13.9-kilometre (8.6-mile) long. It is divided into two parts: Salt Lake Sector V to Sealdah, and Esplanade to Howrah Maidan. Line 3 is 7.75-kilometre (4.82-mile) long. It runs from Joka to Majerhat. Line 6 is 5.4-kilometre (3.4-mile). It runs from Kavi Subhash to Hemanta Mukhopadhyay. The total length of the Kolkata Metro is 59.38 kilometres (36.90 miles).[3][4] Other than these four active lines, there are two more metro lines to be opened.

The Kolkata Metro is is the fourth-longest active metro network in India after the Delhi Metro, Namma Metro and the Hyderabad Metro. It is a mix of underground, at-grade and elevated (higher than the ground) stations. It used both broad-gauge and standard-gauge tracks. Trains run between 06:55 and 22:30 IST. The fares (money to use the trains) of the rapid transit system are between ₹5 to ₹50.

Then it became longer from Kavi Nazrul to Kavi Subhash in 2010. After that, the line became 2.59-kilometre (1.61-mile) longer from Dum Dum to Noapara in 2013. The Dum Dum–Noapara part of the line is elevated (higher than the ground).[9][10][11] Finally, the line became 4.13-kilometre (2.57-mile) longer from Noapara to Dakshineswar in 2021.[12]
