Pacific National is one of Australia's largest private rail freight businesses. Originally a joint venture between Patrick Corporation and Toll Holdings; it is now a wholly owned subsidiary of Asciano Limited following the restructure of Toll Holdings.

In February 2002, the mainly Australian Government-owned National Rail Corporation's freight operations and rollingstock were combined with the New South Wales Government-owned FreightCorp and sold to Toll Holdings and Patrick Corporation as Pacific National.

In 2004, Pacific National purchased Australian Transport Network, operator of TasRail. In the same year, Pacific National also acquired Freight Australia, operator of freight services in Victoria, giving Pacific National control of the Victorian non-urban rail track, excluding the interstate network which is controlled by the Australian Rail Track Corporation.
