The EMD F2 was a freight-hauling diesel locomotive built by General Motors Electro-Motive Division between July 1946 and November 1946.

It succeeded the FT model in GM-EMD's F-unit sequence, and was replaced in turn by the F3.

The F2 was in many respects a transitional type between those two; it kept the 1,350 hp (1,010 kW) rated D8 generator from the FT due to late development of the new D12 generator intended for the F3, but in a revised carbody design and internal layout that would be continued through the rest of the F-unit series.

They were built with what has become known as 'Type 1' side panels, with three portholes and no filter grilles, but this was carried over into early F3 production and in any case, could be changed later by the customer.

They also had four radiator fans at the center of the unit next to each other in line on the roof instead of two at each end.
