The MRT Orange Line (Thai: รถไฟฟ้ามหานคร สายสีส้ม) is a rapid transit line of the Mass Rapid Transit Authority of Thailand (MRTA) in the Bangkok Metropolitan Area, Thailand. When fully completed, the MRT Orange line will be 35.9 km (22.3 mi) long with 29 stations (7 stations will be elevated for 8.9 km (5.5 mi) and 22 will be underground for 27 km (16.8 mi)), including an interchange with the current Thailand Cultural Centre Station of MRT Blue Line).

The line is divided into two sections; the 22.5 km (14.0 mi) Eastern section from Yaek Rom Klao to Thailand Cultural Centre[1][2] and the 2nd phase, 13.4 km (8.3 mi) Western section from Thailand Cultural Centre to Bang Khun Non. Construction of the 22.5 km (14.0 mi) Eastern Section started in June 2017.

The line cannot open until a signalling system is installed and rolling stock is ordered, both of which have not been tendered as the processes have been delayed due to problems with the western extension tender process. The line is not expected to open until August 2025[3] or more likely late 2025 or early 2026.[4] Then it was later delayed again to 2028.

By the end of April 2023, construction had progressed to 99.50%.[5]
