The Shanghai Metro is the urban rapid transit system of China's largest city, Shanghai. The system incorporates both subway (地铁) and light rail (轻轨) lines. It opened in 1995, making Shanghai the third city in Mainland China, after Beijing and Tianjin, to have a rapid transit system. Since then, the Shanghai Metro has become one of the fastest-growing rapid transit systems in the world.

As of 2011, there are eleven metro lines (excluding the Shanghai Maglev Train), 277 stations and over 434 kilometres (270 mi) of tracks in operation, the longest network in the world. The Shanghai Metro delivered 1.884 billion rides in 2010, the fourth busiest in the world. It set a daily ridership record of 7.548 million on October 22, 2010. The system continues to grow, with new lines and extensions of old lines currently under construction.
