The Hamersley Ranges is a mountainous region of the Pilbara, Western Australia. The range runs from the Fortescue River in the northeast, 460 km south. The range contains Western Australia's highest point, Mount Meharry, which reaches approximately AHD. There are many extensively-eroded gorges, such as Wittenoom Gorge. The twenty highest peaks in Western Australia are in the Hamersley Range. Geologically, they are some of the most ancient regions of the earth's crust known as the Pilbara craton.
Some of the Peaks found in the range include Mount Nameless (), Mount Reeder Nichols (), Mount Samson (), Mount Truchanas () and Mount Tom Price ().
The range contains large deposits of iron ore, the source of a large proportion of Australia's iron ore. It is predominately in the Banded Iron Formation (BIF) - also known as the Brockman iron formation   
Western Australia's major iron producers have mines, communities and railways that occur along the range  Rio Tinto operates several iron ore mines within the range including Marandoo, Brockman, Channar, West Angelas and Paraburdoo. Over 100 million tonnes of iron ore is removed from the range every year.
