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 similar to the Dash 9-44CW, but uses AC traction motors instead of DC, with a separate inverter per motor.

3,018 units were built for North American railroads over an 11-year production and 540 AC44i units for the Brazilian railroads. In 2005, all Class I freight railroads except Norfolk Southern and Canadian National owned at least one AC4400CW. Norfolk Southern ordered the very similar C40-9Ws, although NS would later acquire 36 former CEFX AC4400CWs in August 2023. As a result of more stringent emissions requirements that came into effect in January 2005, GE no longer offers the AC4400CW, replacing it with the ES44AC.
