The MRT Kajang Line, previously known as the MRT Sungai Buloh–Kajang Line, is a Mass Rapid Transit (MRT) line servicing the Klang Valley, Malaysia. It is the second fully automated and driverless rail system in the Klang Valley region after the LRT Kelana Jaya Line. Owned by MRT Corp and operated as part of the Rapid KL system by Rapid Rail, it forms part of the Klang Valley Integrated Transit System. The line is numbered 9 and coloured green on official transit maps.
It is one of three planned MRT rail lines under the Klang Valley Mass Rapid Transit Project by MRT Corp. Phase 1 operations between and commenced service on 16 December 2016. Phase 2 operations between Muzium Negara and Kajang station was opened on 17 July 2017, as a free shuttle service, by former Malaysian Prime Minister, Najib Razak in a ceremony at the Tun Razak Exchange station. Full revenue service between Sungai Buloh and Kajang began the following day.
In September 2008, Executive Director of SPNB said that a section of the line in central Kuala Lumpur will be underground, serving 5 stations. However, the locations of underground stations were not announced. It was during this time that the line was said to be with 32 stations in total, which would serve areas of Bandar Utama, Bangsar, KL Sentral, Bukit Bintang, Bandar Tasik Selatan and Cheras. The line was being considered for as a Mass Rapid Transit (MRT) system after taking into consideration the catchment area serving a population of 878,000. It was also reported that the detailed design stage for the line would commence in the second quarter of 2009 and the opening date is expected to be in 2014.
Unofficial statements in 2009 claimed that the proposed line was changed to an MRT line. In June 2010, during the tabling of the 10th Malaysia Plan, Prime Minister Najib Tun Razak announced that the government was now considering a RM36 billion Klang Valley MRT proposal from Gamuda Berhad and MMC Corporation Berhad, which is the largest national infrastructure project. The proposal includes 3 lines, including one which is similar to the Kota Damansara—Cheras proposal. The MRT lines were to be mostly underground with stations to apart in areas with high demand. The concept was envisioned to be inspired by Singapore's Mass Rapid Transit (MRT) system. The project, aimed to improve public transport in the Klang Valley, was approved by the Malaysian cabinet on 16 December 2010 and construction of the first line from Sungai Buloh to Kajang would begin in July 2011 with a duration of five to six years. Gross national income from these future lines is between RM3 bil and RM12 bil. The government had appointed MMC-Gamuda JV Sdn Bhd as Project Delivery Partner where it would play the role project manager, supervised by the Land Public Transport Commission (SPAD). The whole project would be divided into nine parcels in which will be done on open tender basis. of the line would be underground and the remaining above ground with 35 new stations. MMC-Gamuda would be barred from bidding for any tender except for tunnelling works (the most expensive portion). Ownership of the lines would be given to SPNB.
To seek for further consultation from the public, SPAD held a 3-month public display of the alignment of the MRT Kajang Line. On 8 July 2011, Najib officially launched the project. The final alignment was adjusted following the public display, having a length of with 31 stations where 16 have Park and Ride facilities. Construction was said to be completed in December 2016 and the line would start operations a month after. On 17 August 2011, the government announced that MRT Corp, a new company under the Finance Ministry had been formed to take control of the project from Prasarana. MRT Corp would be the asset owner of the project and officially take over the project from Prasarana on 1 September 2011. After the MRT project was formally launched on 8 July 2011, the following amendments have been made to the original proposed alignment following the public display exercise between March and May 2011:
On 1 November 2011, the 70's Klang bus stand ceased operations and was demolished to make way for the underground platforms and new entrances of Pasar Seni station. When construction of the station is completed, a new bus hub will be reconstructed. On 1 August 2012, MRT Corp announced that the project was in active construction phase. MRT Corp said that the project cost would not exceed the limit of RM23 billion. The first section between Sungai Buloh and Semantan was expected to open in December 2016, with the entire line opening in July 2017.
On 30 May 2013, tunnel excavation works for the Kajang Line began with the world's first Variable Density Tunnel Boring Machine (VDTBM). This TBM was jointly designed by MMC Gamuda KVMRT Tunnelling and Herrenknecht AG, a German company. Commencement of tunnelling works was launched by former Malaysian Prime Minister Najib Tun Razak at the Cochrane Launch Shaft, which would later become the Cochrane MRT station. The shaft is deep and this TBM was to dig a distance of towards Pasar Rakyat (now Tun Razak Exchange) station. 10 TBMs were used to construct the tunnelled section of the line, where 6 are Variable Density and 4 are Earth Pressure Balance TBMs. The tunnels are to have a diameter of , where the first breakthrough of the TBM excavations occurred on 25 December 2013.
The fare of this part of the line and its feeder bus routes was free of charge until 16 January 2017. Two days later, MRT Corp confirms cost of 51 km of Kajang Line would be RM21 billion. On 17 July 2017, Phase Two of the line from Semantan to Kajang station began operations.
The line is operated by a subsidiary of Prasarana Malaysia, Rapid Rail.

In the second quarter of 2018, the quarterly ridership is a little short of 12 million, following an overall rising trend. However, the line is deemed to have inadequate ridership to cover the construction, operation and maintenance costs. A target of 250,000 daily passengers is required for the line to break even with its operation costs.
