The MRT Purple line (Thai: รถไฟฟ้ามหานคร สายสีม่วง) or MRT Chalong Ratchatham line (Thai: รถไฟฟ้ามหานคร สายฉลองรัชธรรม) is Bangkok's fifth rapid transit line, following the Sukhumvit Line, Silom Line, MRT Blue Line, and Airport Rail Link. The line is 23 km (14 mi) long,[2] serving the north-western area of Bangkok running from Tao Poon to Klong Bang Phai in Nonthaburi Province.

The line opened on 6 August 2016.[3][2] It is the second line of MRT system and is operated by BEM under a concession contract. Daily ridership is 70,000.[4][5]

A 23.63 km (14.68 mi), 17 station southern extension of the line consisting of a 14.3 km (8.89 mi) underground section and a 9.3 km (5.78 mi) elevated section [6] commenced construction in August 2022. The cost of the southern extension is 82 billion baht and it is planned to open at the end of 2027.[7] By the end of May 2023, construction had progressed to 11.50%.[8]
