The AustralAsia Railway Corporation is a statutory body set up to represent the interests of the South Australian and Northern Territory Governments during the construction and operations of the AustralAsia Railway.

This railway comprises 824 kilometre standard gauge section from Tarcoola to Alice Springs that opened in 1980 and the new 1420 kilometre section from Alice Springs to Darwin that opened in 2004.

The Corporation was set up in 1997 to manage the awarding of a Build, Own, Operate and Transfer back (BOOT) concession for the AustralAsia Railway and to enter into contractual arrangements with the successful consortium (Asia Pacific Transport Pty Ltd) and its successor Genesee and Wyoming.

It was established under the AustralAsia Railway Corporation Act 1996 (NT) and supported by South Australia through complementary legislation.
