The Shanghai trolleybus system is a system of trolleybuses forming part of the public transport network in the city of Shanghai, China. Of more than 300 trolleybus systems in operation worldwide (as of 2011),^[1] the Shanghai system is the oldest.^[2][3] The system turned 100 years old in November 2014 and was the first trolleybus system anywhere in the world to reach that milestone.^[4]

For many years, the Shanghai system was also one of the largest in the world,^[5] once comprising more than 20 routes and more than 900 vehicles in 1994, accounting for 30% of Shanghai's bus ridership. However the system started to decline in scale and service levels in the late 90s and throughout the 2000s with the fleet shrinking to 150 vehicles in 2012. Those smaller figures still make it one of the largest systems in operation outside the former Soviet Union countries. Since then, the trolleybus network is being expanded with a new expanded fleet of 300 trolleybuses for the 12 surviving lines and the introduction of new eBRT lines using trolleybuses in reserved lanes.
