The Chennai Metro is a rapid transit system serving the city of Chennai, India. Operated by Chennai Metro Rail Limited (CMRL) – a joint venture between the Government of India and the Government of Tamil Nadu, the network consists of two lines and spans 54.1 km (33.6 mi). The system uses standard gauge and has 41 underground and elevated stations.

Planning for the Metro started in 2007-08 with construction commencing in February 2009. After testing in 2014, the first segment of the metro between the Alandur and Koyambedu stations on the Green Line began operations on 29 June 2015. On 21 September 2016, operations on the Blue Line commenced between Chennai Airport and Little Mount. The underground stretch from AG-DMS to Washermanpet of Blue Line opened on 10 February 2019, completing phase 1 of the Metro.

Three more lines covering a length of 118.9 km (73.9 mi) are under construction as part of the second phase. The Chennai Mass Rapid Transit System, operated by Indian Railways, is planned to be incorporated into the Chennai Metro. A light rail has been proposed to connect Tambaram of the Chennai suburban rail network with Velachery on the MRTS. Further extensions are also planned for the three lines under construction.
