The Indian locomotive class WDM-3 was a type of diesel-hydraulic locomotive that was developed by Henschel for Indian Railways in 1962. The model name "WDM-3" stood for broad gauge (W), Diesel (D), Mixed traffic (M) engine, 3rd generation (3). These locomotives were put into service between 1970 and 1971, and a total of eight were built between 1962 and 1970. However, they were decommissioned at Gooty in 1995 and are now retired from service.

These diesel-hydraulic locomotives were not related to the ALCO WDM-3A, despite their similar name.
