Line 3 of the Guangzhou Metro is a 74.83-kilometer (46.50 mi) rapid transit line connects Haibang to Airport North (Terminal 2). The entire line, including all track and stations, is located in tunnels. Its 67.33 km (41.84 mi) main branch, excluding the 7.5 km (4.66 mi) branch between Tianhe Coach Terminal and Tiyu Xilu, is now the third longest continuous subway tunnel in the world, and the longest rail tunnel of any kind (surpassing the Gotthard Base Tunnel in Switzerland).

Line 3 is split into two sections, Shiqiao line (main line, from Haibang to Tianhe Coach Terminal) and Airport line (northern branch, Tiyu Xilu to Airport North), and are branded with the colour orange. The line is extremely congested, with numerous sections officially operating over 100% capacity. The line uses Seltrac S40 communications-based train control from Alcatel.
