The Class ED10 (ED10形) was a Bo-Bo wheel arrangement electric locomotive that operated in Japan from 1922.

The two locomotives in the class were designed and built by Westinghouse Electric (electrical components) and Baldwin (mechanical components) in 1922. Originally designated "Class 1000", the locomotives were reclassified ED10 in 1928. The unit has a Bo-Bo wheel arrangement and is powered by four DC traction motors producing a total of 1,100 horsepower. The ED10 weighs just over 67 tons and has a top speed of 40 miles per hour (64 km/h).
