The ČSD class E 422.0 (Class 100 since 1987) is a Czech electric locomotive, intended for secondary lines electrified at 1.5kV DC.

The locomotives were built for the Tábor–Bechyně and Rybník–Lipno nad Vltavou railways, both of which were electrified with non standard 1.5kV DC electrification.

After approval testing had been carried out, and modifications made, the locomotives entered service in July 1957.

Locomotive 2 is currently owned by the National Technical Museum, and stored at Chomutov.
