The Roy Hill railway, officially the Roy Hill Infrastructure railway, owned and operated by Hancock Prospecting, is a private rail network in the Pilbara region of Western Australia built to carry iron ore.

In addition to the Hancock Prospecting network, several other independent iron ore rail lines comprise the Pilbara Iron Ore Railways: An application to construct the Roy Hill railway was lodged with the Environmental Protection Authority of Western Australia in October 2010.

In the original application, the operator of the railway line, Roy Hill Infrastructure Pty Ltd, proposed to build a 320 km (198.84 mi) long railway line from the Roy Hill mine to the Port of Port Hedland.

[2] The route change was necessary because Roy Hill Infrastructure was unable to obtain permission from third-party mining lease-holders to construct the railway as originally approved.

[4] The construction of the railway commenced in 2012 and was completed after 27 months, with the first ore train traveling the line in December 2015.
