The Indian locomotive class WAP-6 was a class of 25 kV AC electric locomotives that was developed in the mid-1990s by Chittaranjan Locomotive Works for Indian Railways. The model name stands for broad gauge (W), AC Current (A), Passenger traffic (P) locomotive, 6th generation (6). They entered service in April 1996. A total of 17 WAP-6 units were built at CLW between 1995 and 1998.

The WAP-6 were intended to be a higher-speed variant of the WAP-4, but were restricted to a top speed of 105 km/h after failing trials. All were based at Asansol (ASN) shed, but after conversion to WAP-4 specifications, they were reallocated to Howrah (HWH) shed.
