Dhaka Metro Railis an approved mass rapid transit system under construction in Dhaka, the capital and the busiest city of Bangladesh. Together with a separate Light rapid transit (LRT) system, it has been long called for to ease the extreme traffic jams and congestion that occur throughout the entire city daily, one of the heaviest in the world. It is a part of the 20-year long Strategic Transport Plan (STP) outlined by the Dhaka Transport Coordination Authority (DTCA), a governmental agency.

As of 2020, the metro rail system consists of one line referred to as the MRT (Mass Rapid Transit) Line-6, with other metro rail lines going to be added in the future.

Construction began on 26 June 2016 with an inauguration ceremony presided over by the Honourable Prime Minister Sheikh Hasina. The civil work is being done by the Italian-Thai Development Public Company Ltd. and Sinohydro Corporation Ltd. JV and a Tokyo-based construction company is developing the depot's land. The track laying work, overhead electric supply work, and signalling system works are being done by Larsen & Toubro construction company of India.
