The Shaoshan 4 (Chinese: 韶山4) is a type of electric locomotive used on the People's Republic of China's national railway system. This locomotive was built by the Zhuzhou Electric Locomotive Works. The power supply was industrial-frequency single-phase AC, and the axle arrangement Bo′Bo′+Bo′Bo′.[1]

In 1993, Zhuzhou Electric Locomotive Works produced SS4G (Chinese: 韶4改). SS4G are very similar to standard SS4, apart from an improved electrical technology.[2]

SS4 Electric Locomotive is an eight shaft fixing reconnection heavy freight electric locomotive which based on two four-axle locomotives connected. One unit, SS4-0043, was damaged in a tunnel during the 2008 Sichuan earthquake.
