Line 7 of the Guangzhou Metro is a rapid transit line in Guangzhou and Foshan, Guangdong Province, China. It is envisioned as a tangential line that runs across southeast Guangzhou and Foshan, allowing for orbital traffic between the suburbs of Shunde, Panyu and Huangpu to avoid the crowded stations in the city center. Line 7's color is light green.

Planning A tangential line serving southern Guangzhou was first proposed in 2002 as the Fangcun-Panyu-Huangpu Line. It would have started at Xilang station on Line 1 in the southwest, running southeast to Nanpu, then east along the northern edge of Panyu District. Interchanges were planned at Dashi and Xinzao with what is now Line 3 and Line 4 respectively. Finally the line would cross the Pearl River to terminate at the Guangzhou Economic and Technological Development Zone.
Subsequently, Line 7's design was greatly revised in 2003, with most of the line realigned further south. It would now start at Guangzhou New Passenger Station, what is now Guangzhou South railway station, with the interchange with Line 3 at Hanxi Changlong station. From here, it would turn northeast to meet Line 4 at Higher Education Mega Center, passing Changzhou Island before crossing the Pearl River west of the original plan into Huangpu District.
By 2010, the line had been split into two stages at Higher Education Mega Center South, with stage 1 being the western section from Guangzhou South Railway Station and stage 2 the eastern section to Dashadong.
Phase 1 On 16 July 2012, Phase 1 of the line received approval from the National Development and Reform Commission. It would run from to , with 9 stations and a total route length of . The line would share Line 3's control center at Dashi.
On 27 May 2014, the first tunnel section was completed, from Guangzhou South Railway Station to Dazhou depot.
By April 2016, tunnelling and the main structure of all stations was complete.
Phase 1 opened for passenger operation on 28 December 2016.
Phase 1 west extension
The plan for west extension of the first phase from to Meidi Dadao in Shunde District, Foshan was approved in October 2015. The construction of the west extension to Shunde began in June 2016. The west extension opened on 1 May 2022. The extension is in length with 8 stations. It has an interchange with Foshan Metro Line 3 at .
Phase 2 The Northern extension to opened on 28 December 2023. It extends the line into Huangpu District, having a total length of with 11 stations, 10 of which are operational ( station is complete, but was not opened pending development in the area). It has interchanges with Line 13 at , Line 5 at , Line 6 at and Line 21 and Huangpu Tram Line 1 at .

Rolling stock During initial planning, Line 7 considered the use of 4 car L-type light metro trains for operation. However, severe congestion issues were created after the opening of Line 3, which only uses low capacity 3 car Type B trains and Line 6 which uses even lower capacity 4 car L-shaped trains, prompted heavy public criticism. Planners subsequently reevaluated the passenger flow forecasts for the entire line of Line 7, and upgraded the design to use 6 car B-type trains. Therefore, at the time of construction of Line 7, the partly completed station structures of Line 7 platforms at Guangzhou South Railway Station and Higher Education Mega Center South station were expanded to accommodate the longer trains.
Type B9 trains were equipped with 36.6-inch LCD displays at the end of each car and above each door.
