The Indian locomotive classes WAM-2 and WAM-3 were 25 kV AC electric locomotives that were imported from Japan in the 1960s for Indian Railways. The model's name stands for broad gauge (W), alternating current (A), Mixed traffic (M) locomotive, 2nd generation (2). A total of 38 WAM-2/3 locomotives were built by a consortium, comprising Mitsubishi, Hitachi and Toshiba, between 1960 and 1964. These locomotives entered service in 1960.

The WAM-2 and WAM-3 classes served both passenger and freight trains for over 40 years. As of January 2020, these locomotives are no longer in service.
