The ChS8 (Russian: ЧС8) is an electric mainline AC passenger locomotive used in Russia and Ukraine.

The 8 axle locomotive was developed for pulling long passenger trains (28–32 carriages) at speeds around 100 km/h or faster. In 1983 the first two experimental locomotives were constructed and delivered to Kyiv for tests and adjustment. In 1987 30 locomotives were built as a mass model. In 1989 last 50 locomotives were built.

As the most powerful AC passenger locomotive in USSR designed for long trains, ChS8 experienced a low demand when after the disintegration of the USSR passenger turnover in both Russia and Ukraine fell significantly. After 2010 Russian railways turned to more energy-effective EP10 and EP20 as powerful locomotives for fast or long passenger trains.
