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.

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.

One unit, SS4-0043, was damaged in a tunnel during the 2008 Sichuan earthquake.
