Aurizon Holdings Limited, formerly QR National, is a freight rail transport company in Australia, and the largest of its kind in the nation. Formerly a Queensland Government-owned company, it was privatised and floated on the ASX in November 2010. The company was originally established in 2004–05 when the coal, bulk, and container transport divisions from Queensland Rail were brought under one banner, as QR National.

On an average day, Aurizon will move in excess of 700,000 t (770,000 tons) of coal, iron ore and other minerals, as well as agricultural products and general freight across the nation. The company transports more than 250 million tonnes of Australian commodities each year, with operations in five Australian states. Aurizon also manages the 2,670 km (1,660 mi) Central Queensland coal network that links mines to coal ports at Bowen, Gladstone and Mackay, and is the largest haulier of iron ore outside the Pilbara.
