The MRT Circle Line, also known as MRT 3, is a proposed thirteenth rail transit line, the third Mass Rapid Transit line and the fifth fully automated and driverless rail system in the Klang Valley region of Malaysia. Once completed, this line would form the first loop line of the Klang Valley Integrated Transit System.
On 17 July 2025, the Minister of Transport approved the Final Railway Scheme for the project. Following a review of the feedback from the 2024 Public Inspection, the project adopted an "Intermediate MRT" (i-MRT) system technology with shorter 4-car trainsets and tighter turning radii to significantly reduce land acquisition. The line is currently in the land acquisition phase with construction expected to begin in 2027 and the line scheduled to be fully operational by 2032.
The circle line will be numbered 13 and coloured blue violet on official transit maps.
