The GE C40-8M was a 6-axle diesel locomotive built by GE Transportation Systems from 1990 to 1994. It was part of the GE Dash 8 Series of freight locomotives, and was often referred to as a Dash 8-40CM.

Mechanically identical to the Dash 8-40CW, the Dash 8-40CM was constructed only for Canadian railways, with a production total of 84 units. It was distinguished from the Dash 8-40CW by the addition of a full-width "Draper Taper" style cowl body, of which they were the last locomotives built with this feature, and the use of a Canadian-specific nose and windshield configuration. The trucks also differ; all units built ride on Dofasco Hi-Ad trucks identical to locomotives built by Montreal Locomotive Works, Bombardier, and Morrison-Knudsen.
