The Circle Line (CCL) is a medium-capacity Mass Rapid Transit (MRT) line in Singapore. It runs in a loop from Dhoby Ghaut station in the city-centre to HarbourFront station in the south via Bishan station in the centre of the country. It also has a branch to Marina Bay station from Promenade station, which will be extended to HarbourFront station from 2026 to form a complete loop. Coloured orange on the rail map, the fully-underground line is approximately 35.5 kilometres (22.1 mi) long with 30 stations. Travelling from one end of the line to the other takes about an hour.

The line was the fourth MRT line to be opened on the network, with the first stage, from Bartley to Marymount station, commencing operations on 28 May 2009. The next stage to Dhoby Ghaut was completed on 17 April 2010 and the next stage to HarbourFront opened on 8 October 2011. A two-station extension to Marina Bay station was opened on 14 January 2012. The last stage of the line from HarbourFront to Marina Bay with stations at Keppel, Cantonment, and Prince Edward Road will be completed in 2026, completing the loop.

It is the second line in Singapore after the North East Line to be completely automated and driverless and is among the world's longest driverless rapid transit lines.^[2] It is also the first medium capacity line in Singapore, with each Circle Line train, the Alstom Metropolis C830 and C830C, having a three-car configuration.
