The EMD GP30 is a 2,250 hp (1,680 kW) four-axle diesel-electric locomotive built by General Motors Electro-Motive Division of La Grange, Illinois between July 1961 and November 1963. A total of 948 units were built for railroads in the United States and Canada (2 only), including 40 cabless B units for the Union Pacific Railroad.

It was the first so-called "second generation" EMD diesel locomotive, and was produced in response to increased competition by a new entrant, General Electric's U25B, which was released in 1959. The GP30 is easily recognizable due to its high profile and stepped cab roof, unique among American locomotives. A number are still in service today in original or rebuilt form.
