The MRT Blue Line (Thai: รถไฟฟ้ามหานคร สายสีน้ำเงิน) or MRT Chaloem Ratchamongkon Line (Thai: รถไฟฟ้ามหานคร สายเฉลิมรัชมงคล) is Bangkok's third rapid transit line, following the Sukhumvit line and Silom line of the BTS Skytrain. It is the first line of the MRT system and is operated by Bangkok Expressway and Metro (BEM). The original 20 km (12.43 mi) MRT Blue Line from Hua Lamphong to Bang Sue opened on 3 July 2004. A 1.2 km (0.75 mi) extension to Tao Poon opened on 11 August 2017. The 15.9 km (9.88 mi) western extension to Lak Song opened for full service on 29 September 2019 and the 11 km (6.84 mi) extension from Tao Poon to Tha Phra to form the quasi loop, opened for full service on 30 March 2020.

The line has a total length of 48 km (29.83 mi), being a quasi circle route of the Bangkok rapid transit network. The MRT Blue line connects major business, residential and cultural areas of Bangkok. In late 2019, the average daily ridership was 400,000.[2] In mid 2021, during a COVID-19 3rd wave in Bangkok ridership plummeted to between 76,000 - 116,000 per weekday.[3]
