Guangzhou–Shenzhen–Hong Kong Express Rail Link (XRL), also known as the Guangshengang XRL, is a high-speed railway line that connects Beijing and Hong Kong (Kowloon) via Guangzhou and Shenzhen.

The Beijing–Guangzhou–Shenzhen–Hong Kong high-speed railway or Jingguangshengang high-speed railway from its Chinese name is a high-speed railway corridor of the CRH passenger service, connecting Beijingxi station in Beijing and Futian station in Shenzhen, Guangdong in less than nine hours of travel time. It is 2,230 kilometres (1,390 mi) long, and is the only Chinese high-speed railway to cross a border that requires immigration and customs clearance. The existing, conventional Jingguang railway runs largely parallel to the line.
