The Shaoshan 7 (Chinese: 韶山7) is a type of electric locomotive used on the People's Republic of China's national railway system.

The design of SS7 was influenced by the 6K, an electric locomotive model imported from Japan.

However, SS7's frequent failure lead to Datong Electric Locomotive Works making improvements to SS7s.

Most of SS7s belong to Liuzhou Locomotive Depot, Nanning Railway Bureau.

SS7Cs' each axis axle load 22 tons, and support head-end power.

SS7D use lightweight design, each axis axle load 21 tons, and support head-end power.
