The MRT Putrajaya Line is the second Mass Rapid Transit (MRT) line in Klang Valley, Malaysia, and the third fully automated and driverless rail system in the country. It was previously known as the MRT Sungai Buloh–Serdang–Putrajaya Line. The line stretches from to Putrajaya and runs through densely populated areas such as Sri Damansara, Kepong, Batu, Jalan Ipoh, Sentul, Kampung Baru, Jalan Tun Razak, KLCC, Tun Razak Exchange, Kuchai Lama, Seri Kembangan and Cyberjaya.

The line is numbered 12 and coloured yellow on official transit maps.

The line was developed and owned by MRT Corp but operated as part of the Rapid KL network by Rapid Rail. It also forms part of the Klang Valley Integrated Transit System.

The line, totalling 57.7 km (35 miles 68 chains) in length, includes annexed from the MRT Kajang Line, making it the longest metro line in Malaysia, and one of the longest driverless rapid transit lines in the world. The line includes a underground section. A total of 37 stations, 11 of them underground, were built.

The MRT then continues towards the towns of Kepong and Jinjang. As of the first phase, the Putrajaya line ends at Kampung Batu. At Jalan Ipoh, the line starts going underground while Jalan Ipoh itself being the only station on the network to be half-sunken/sub-surface. The line carries under the Jalan Ipoh to Titiwangsa which will interchange with the LRT Ampang/Sri Petaling, KL Monorail and future MRT Circle lines. The line then runs under the Hospital Kuala Lumpur and meets the connecting station to LRT Kelana Jaya line (also underground) at Ampang Park. Persiaran KLCC serves as a second station in the KLCC subdistrict, itself also served by the LRT Kelana Jaya Line. The line continues to Tun Razak Exchange, interchanging with the Kajang line. The Putrajaya Line reunites with the Ampang/Sri Petaling line at Chan Sow Lin.

After thru provisional Bandar Malaysia North and South stations, the MRT Putrajaya line resurfaces at Taman Desa portal, just before Kuchai station. Once again, the line meets with the LRT Sri Petaling line at Sungai Besi, then continuing to serve Seri Kembangan. Following this, the line briefly parallels Seremban Line and KLIA Transit (airport express) until Serdang Raya Selatan, and veers off to Universiti Putra Malaysia and the Seri Kembangan subdistrict. The MRT line then enters Sepang constituency, having 3 stops including two in Cyberjaya, before ending at Putrajaya Sentral, where it interchanges with the KLIA Transit. The station may be integrated with the proposed Putrajaya Monorail in the future. Putrajaya Sentral will also be the southernmost station under the Rapid KL.

The project was officially approved by the Federal government in March 2015 and allocated RM23 billion in the 2015 Budget and construction was expected to begin by November 2015. However, construction was delayed due to adjustments to the alignment to extend the line to Putrajaya and to provide connectivity to the proposed High Speed Rail project. Construction officially begun in September 2016 with a groundbreaking ceremony at the site of the future Putrajaya Sentral MRT station by former Prime Minister Dato' Seri Najib Razak.

On 10 October 2017 at around 5pm, an explosion occurred at the Mass Rapid Transit (MRT) station construction site in Bandar Malaysia. According to the police, it was believed that the explosion happened because of an old unexploded bomb from the Second World War based on their initial investigation. Three Bangladesh workers were seriously injured and two of them lost their legs while another suffered injuries on the hands and legs. One of the workers later succumbed to his injuries and died in the evening of the same day.
