The Indian locomotive class WAG-5 is a class of 25 kV AC electric locomotives that was developed in 1978 by Chittaranjan Locomotive Works for Indian Railways. The model name stands for broad gauge (W), alternating current (A), goods traffic (G) engine, 5th generation (5). They entered service in 1980. A total of 1196 WAG-5 were built at CLW and BHEL between 1978 and 1998, which made them the most numerous class of mainline electric locomotive until the introduction of its successor, the WAG-7.

The WAG-5 is one of the most successful locomotives of Indian Railways currently serving both freight and passenger trains for over 43 years. This class provided the basic design for a number of other locomotives, like WAG-7 and the WCM-6. However, with the advent of new 3-phase locomotives like WAG-9 and WAG-12, the WAG-5 locomotives were relegated to hauling smaller passenger trains and now the aging fleet of WAG-5 locomotives is rapidly being withdrawn from mainline duties and scrapped.
