The Shanghai Ring Expressway (Chinese: 上海绕城高速公路; pinyin: Shànghǎi Ràochéng Gāosù Gōnglù), designated G1503, formerly designated as A30 and G1501, and also known as the Shanghai Suburb Ring Expressway (Chinese: 上海郊环高速公路; pinyin: Shànghǎi Jiāohuán Gāosù Gōnglù), is a 209.22-kilometre-long ring expressway (130.00 mi)[1] that encircles Shanghai, a direct-controlled municipality in the People's Republic of China.

It is entirely in Shanghai, except for a small section in the nearby province of Jiangsu at its northwest end.

As the tunnel ends in Pudong New Area, it becomes an elevated highway for a short portion, curving southeast and then south, reaching the Wuzhou Avenue Interchange.

At Tongji Road, the expressway curves to the south, paralleling the elevated Line 3 of the Shanghai Metro.

At the southern end of Tongji Elevated Road, the Shanghai Ring Expressway returns to its kilometre zero marker.
