The Shanghai–Nanjing Intercity High-Speed Railway or Huning Intercity High-Speed Railway (simplified Chinese: 沪宁城际高速铁路; traditional Chinese: 滬寧城際高速鐵路; pinyin: Hùníng Gāosù Tiělù) is a 301-kilometre (187 mi) long high-speed rail line between Shanghai and Nanjing in the People's Republic of China. Hu and Ning are, respectively, shorthand Chinese names for Shanghai and Nanjing. The Huning Intercity High-Speed Railway largely follows the route of the preexisting Nanjing-Shanghai section of the conventional Beijing-Shanghai Railway and the high speed Beijing–Shanghai High-Speed Railway. Construction of this high-speed railway began in July 2008. The line went into test operations in early April 2010, and opened for full service on July 1, 2010. The line has a design speed of 350 km/h (217 mph). The journey time between the two cities has been shortened from 120 minutes to 73 minutes on non-stop service.

According to the arrangements of related departments, 120 pairs of trains are operating on the line, and the time interval between services is 5 minutes at the shortest.

The railway links major cities in the Yangtze River Delta, including Suzhou, Wuxi, Changzhou, and Zhenjiang, effectively making the southern Jiangsu city-belt operate like a single metropolitan region.

The Shanghai–Nanjing Intercity High-Speed Railway is also used by the majority of high-speed trains leaving Shanghai's terminals for Wuhan, Yichang, Chongqing, and Chengdu thus making it de facto a part of the Shanghai–Wuhan–Chengdu High-Speed Railway.
