The British Rail Class 59 is a fleet of Co-Co diesel-electric locomotives built between 1985 and 1995 by the Electro-Motive Division of General Motors for use in Great Britain. A total of 15 locomotives were built for three different operators.

They were both the first privately-owned diesel locomotives, and the first US-made diesel locomotives, to operate regularly on British mainline railways. One member of the class operated in Germany between 1997 and 2014, before returning to the UK.
