The NR class are a class of Australian diesel locomotive built by A Goninan & Co for National Rail between 1996 and 1998. They are currently operated by Pacific National. The QR National 5000 (and 5020) class locomotives, and all the C44aci model locomotives build by UGL Rail at Broadmeadow adopted the design from the NR Class, but with a variety of features to set them apart from each other and the NR Class locomotives.

Upon commencing operations in April 1993 the National Rail inherited a diverse collection of rolling stock to operate interstate freight operations in Australia. The fleet included locomotives of mixed age and power leased from FreightCorp, V/Line and Australian National.

In September 1995 A Goninan & Co were awarded a contract for 120 locomotives from National Rail which were built at their Broadmeadow (NR1-NR60) and Bassendean (NR61-NR120) factories. The frames were built at Hexham and the bogies at Goninan's Landsdowne Engineering subsidiary in Taree.

The first locomotive to be completed was NR61 which performed its first trial on 18 September 1996 between Midland and Jumpakine. The first Broadmeadow built unit first ran on 23 September 1996. The first units were delivered without National Rail branding or logos, but later units were delivered in full livery. Testing of the units was carried out on the NSW Main Northern line between Werris Creek and Maitland using ballast wagons and 442 class locomotives in dynamic braking mode as dynamic loads. Each locomotive was required to accumulate 10,000 km of trouble free running before acceptance. In February 1998 Broadmeadow delivered the last NR class.
