The GE AC4400CW, sometimes referred as 'AC44CW' is a 4,400 horsepower (3,300 kW) diesel-electric locomotive that was built by GE Transportation Systems between 1993 and 2004. It is like the Dash 9-44CW, but features AC traction motors instead of DC, with a separate inverter per motor. In appearance, the AC4400CW is somewhat similar to GE's more powerful locomotive, the AC6000CW.

2,834 units were built for North American railroads over an 11-year production.
